Filled chocolate truffles

I've heard "truffle" used two ways with chocolate -- either simple balls of ganache covered in cocoa / sugar / chopped nuts, or a formed chocolate shell holding some kind of filling.  The former are pretty straightforward, but the latter are generally the domain of professional chocolate shops.  So of course, that's what we wanted to make for our friends and family this Christmas!  Although it takes time, it's not that hard to produce an attractive -- and tasty -- result!  (Flawless is still for the pros, though.)

Ingredients & Equipment

• Couverture chocolate.  This is high quality chocolate containing extra cocoa butter, and is used for the chocolate shell.  The extra fat (cocoa butter) allows the chocolate to be tempered, producing a hard, shiny coat.  Although I haven't tried it myself, the lore is that trying to use grocery-store chocolate for the shell will give poor results.  (For a ganache filling, though, cheaper stuff seems fine to me.)  The best deal I found was $15 + $10 shipping for 1 kg (2.2 lbs) of Callebaut from Golda's Kitchen on Amazon.  I got about 4 dozen truffles per kilogram, but there's always a little waste at the end, so order at least 2 kg.
• Chocolate molds.  These are simple plastic trays that for molding the truffles.  Lots of different sizes are available.  The stated volumes seem to be for solid chocolates, so you'll get more for filled ones.  I bought three 6 x 1 oz molds from Amazon.  More molds make faster work, but more than about four would be hard to manage at one time.
• Instant-read digital thermometer.  Temperature (within 1 degree F) is critical for getting a good temper on the chocolate.  Don't skip this.
• Marble slab / stone counter / sheet pan.  Ideally, you'd have a smooth, hard stone surface for tempering the chocolate.  But I didn't, so I used the back of a cookie sheet.  It's not ideal, but it's certainly workable.  Make sure it's flat and clean.

Tempering the Chocolate


Tempering chocolate consists of melting it completely and then cooling it in a controlled way.  The even cooling causes the fats to solidify in the uniform structure that produces a smooth, hard, shiny surface when the chocolate sets.

If you didn't buy callets (chips), chop the chocolate.  You'll want at least enough to fill all your molds once.  More won't hurt, you can re-use any leftovers.  Melt them in a double boiler with 140 F water, top vessel not touching the water.  Stir gently but continuously -- getting the chocolate over 140 F will scorch it, but you don't want to whip in any air.  Also watch out for water -- even a small amount of water in the chocolate will ruin it.  Keep stirring until the chocolate gets to 115 - 120 F.  (Temperatures here are for dark chocolate;  they vary somewhat for white or milk chocolate.)

Pour most (~3/4) of the chocolate out on your work surface, set the rest aside, off the heat.  Spread it thin to help it cool, and keep folding it back on itself to mix it.  I used an offset spatula in one hand and a metal bench scraper in the other.  When the chocolate gets cool enough, it will abruptly set up into a thick paste.  Scoop this back into your double boiler and stir until smooth.  If the combined chocolate is now down to 82 - 83 F, you're done.  Otherwise, pour some out and repeat -- you'll need less (maybe half) and it will set up faster (since it started off cooler).

The chocolate is now tempered.  (You can test this by dipping a corner of parchment in the paper, folding it back on itself, and freezing for a minute or two.  When set, it should break with a crisp crack.)  But to work with it, you'll want to re-warm it over the double boiler to 87 - 90 F.  Above ~93 F, the chocolate will start to lose its temper, so keep a thermometer in it while you're doing this.  You'll probably need to re-warm the chocolate before each of the following steps.

Pour the warm chocolate into the prepared molds, filling them completely.  It works best if you stop just shy of the rim -- too full and the truffles will have a little rim around the bottom.  Let the molds sit at room temperature for 4 - 5 minutes (no more), then turn them upside down and give a gentle shake over your work surface.  The molten centers should fall out, leaving chocolate shells in the molds.  Freeze the molds for 5 minutes to fully set the shells.  Scoop the chocolate on the work surface back into your double boiler to reuse.

Fill the shells with whatever you like (see below for suggestions).  Fillings should be cool (no more than 80 F) so they don't melt the shells.  If the filling seems thin, freeze for a another 5 minutes before capping.  (Otherwise, the cap chocolate may sink into it!)  To cap, pour a little more tempered couverture chocolate over the filling.  I find shaking the mold gently after pouring each one helps the cap spread out smoothly.  Work as quickly as you can;  the chocolate will want to set up almost immediately.  Freeze the truffles for 15 minutes to fully set them, then gently turn them out of the molds.  They should come out very easily -- I think the freezing makes them pull away from the mold slightly.

We decorated them with edible glitter dust.  We brushed the truffles with a little water to make it stick -- water doesn't seem to hurt them once they're solid.  We also tried colored icing on a later batch, which worked OK, but didn't look quite as good.

Whisky Ganache Filling

In a microwave-safe bowl, combine

1. 8 oz chocolate chips
2. 4 oz (1/2 c) heavy cream

Microwave about 30 seconds, until chocolate is soft.  Stir gently until smooth.  Stir in

1. 2 oz (4 T) Scotch whiskey

Let sit to cool to 80 F or less.

Any sort of liquor can be substituted:  kirsch, Chambord, creme de menthe, triple sec, etc. are all good.  We even considered tequila with candied lime peel and sea salt, but never got around to it.

Cabernet Reduction Filling

This is basically a wine jelly, a filling we invented for my father-in-law.  It's derived from this recipe.  In a small bowl, place

1. 1 packet (0.25 oz) unflavored gelatin, such as Knox
2. 3 T red wine

The wine will hydrate the gelatin.  I found it best to pour the wine over top of it.  In a medium saucepan, combine

1. 1 bottle (750 ml) red wine (3 T reserved above)
2. 6 T sugar

Boil the mix until reduced to 3/4 c (6 fl oz).  Pour it into a Pyrex measuring cup to make sure;  this needs to be pretty accurate, within about a quarter ounce.  Stir in the hydrated gelatin until melted.  This filling will probably still be liquid when you fill the truffles, it takes hours or days to set, but it does eventually set.

Dulce de Leche Filling

This is a wonderful, easy caramel sauce that I love.  Simply submerse an unopened 14 oz can of sweetened condensed milk into a saucepan of water, and simmer for 90 minutes.  Do not, under any circumstances, allow the pan to run dry, or you may get an exploding can of hot caramel.  If you keep it at a simmer and keep the pan covered you should have no problem.  The label will probably fall off, but the canned caramel can be stored in the pantry for months.  Just pop the top and fill the chocolate shells when you're finally ready.  Do two or three cans at once so you'll have extra for pound cake, cheesecake, ice cream, etc.

Bacon caramels with smoked salt

The holidays always make me want to bake.  And for some reason, they particularly make me want to try something new or more elaborate than I've done before.  So this year, I've been making a lot of candy for Christmas.  Even as a kid, I was at least as partial to caramel flavors as to chocolate.  I also have my mother's love of salt, so salted caramel is a near-perfect candy already.

Which brings me to bacon caramel.  This variation was inspired by my brother-in-law Tommy, who is (tragically!) allergic to chocolate, and who generally prefers meat to candy.  When I tell people about this flavor combo, I usually get raised eyebrows at a minimum.  I, too, was skeptical.  But then the folks who dip their bacon in the leftover pancake syrup start to reconsider.  And after testing on a dozen friends and co-workers, there's been a unanimous thumbs up.

I wish I could claim to have thought of it first, but a quick Google proves I didn't.  Still, I think my version packs in more bacon deliciousness than any of the other contenders!  What follows is a basic recipe for caramels from the Ultimate Southern Living Cookbook, followed by the bacon version and two other sweet variations.

Basic Caramels

If using a candy thermometer, put it in a pot of boiling water to see how far off 212 F it is.  Match the depth of the water to the expected depth of the caramel mixture.  If you're inclined to skip this step, don't use a thermometer at all -- it will likely do you more harm than good.

In a large, deep pot, combine

1. 2 sticks (1 c) butter
2. 2 c (14 oz) granulated sugar
3. 2 c (16 oz) light corn syrup
4. 1 c heavy whipping cream

Stainless steel is preferable because it makes it easier to judge the color of the caramel, but anything will work.  Use a big pot, much bigger than you think you need;  this stuff expands a lot.  Cook over medium to around 224 F, stirring occasionally.  Adjust the target temperature based on how far off your thermometer is.  If it read e.g. 206 in the boiling water (6 degrees off), you'll want to target 224 - 6 = 218 F.  While it's bubbling, cover it with a lid for a few minutes -- the steam should wash down in stray sugar crystals stuck to the sides.  (With so much corn syrup, I don't think there's much danger of crystallization, but it can't hurt.)  Now stir in

1. 1 c heavy whipping cream

I'm not sure why recipes have you add the cream in two additions.  I'd guess only the final temperature matters, but I keep doing it this way out of superstition.  Now the precise part:  cook to exactly 246 - 248 F (again adjusted for your thermometer).  The mixture will take on that signature caramel color and a thick, stringy texture when stirred (reminiscent of a starter sponge for yeast dough).  A degree more or less at this stage makes a noticeable difference in the texture of the candy:  too low, and the caramel will ooze;  too high, and the caramel will be brittle.  I like to reduce the heat to low at this point so the caramel cooks a little more slowly, and I have more wiggle room.

About 5 degrees before done, start dropping spoonfuls of caramel into a little bowl of ice water.  Squeeze it flat with your fingers to help it chill.  When it's room temperature, pull it out and chew to check the texture.  When it's done, the super thin and spindly edges will probably crack (because they got colder) and the body of it will have a pleasantly firm chew.  It doesn't hurt to pull the pot off the heat while you're checking, so it doesn't get away from you.

Finally, stir in

1. 2 t vanilla extract

and any other last-minute additions.  Pour into a well-greased 9 x 13 baking pan.  I like to line mine with foil first (nonstick, if you've got it) to make things easier.  Sprinkle with

1. Fleur de sel or other coarse salt

if you like.  Let cool to room temperature, then cut into squares.

Bacon Caramels (original)

Before starting, thoroughly cook

1. 1/2 lb bacon, chopped

Stir often and lower the heat as it approaches done, to avoid burning.  Continue cooking until all fat is rendered and all bacon is very crisp.  Transfer bacon to paper towel-lined plate.  Chop bacon finely.  Pour hot bacon grease through a coffee filter set in a strainer, into a heatproof measuring cup.  (This is to remove any bits that might burn or spoil later.)  Use bacon grease to replace an equal amount of butter in the basic recipe (about 1/4 cup, half a stick).  Fold bacon in at the end, with the vanilla.  I like to use

1. applewood-smoked sea salt

from the Spice & Tea Exchange to top the caramels and really up that smokey bacon flavor.

Pecan Praline Caramels (original)

Replace 1 c of granulated sugar with 1 c brown sugar, and fold in 8 oz chopped toasted pecans with the vanilla.  Top with salt.

Ginger Fleur-de-sel Caramels (original)

Before starting, place ~2 oz peeled, thin-sliced ginger in a saucepan with the cream, and bring to a gentle simmer.  Turn off the heat and leave the ginger to steep for at least 15 minutes.  This imparts a subtle ginger note to the caramels without being too obvious.
