This is, without a doubt, the most popular candy that I make. Similar to the almond toffee sold in pink tins (except years fresher), this toffee compresses the flavor of butter and almonds into a compact package. I'm a big fan of dark chocolate, so I naturally enrobe these in 70% - 72% dark chocolate before coating with chopped almonds. This is a big recipe, but there are economies of scale and I still make three batches during the holidays. If you are just curious, reduce quantities in half if you must—but you will wish you made more.

Coating
1 1/2 pounds dark chocolate
2-3 pounds chopped unsalted, dry roasted almonds

Chop nuts for coating and sift away almond flour.
You can use pre-chopped almonds, but chopping them yourself yields a better tasting toffee. You can chop your almonds a week or more in advance. Use a food processor to chop all of the almonds. To reduce the risk of scorching and improve the consistency of the almond coating, use a coarse sieve to filter out the fine almond powder. Discard the powder or save it for a recipe calling for almond flour. Store the almonds in an air tight container until ready to use.

Oil marble board with safflower oil.
If you have marble counters, you could skip running out and getting a marble board. It is actually hard to find large enough ones, though I imagine you could use a silpat mat and any cutting board or surface. Read the rest of the instructions below and get anything else you need handy: phone, remote control, hot mitt, beer(s)—whatever. You are going to be stirring from here on out, so get comfortable.

Cook the toffee mixture minus almonds until it reaches 260° F (127° C).
Melt the butter in a copper pot until melted. Melt the butter slowly over low heat—if the butter separates into fat and clarified butter there is a good chance it will never come back together (this is bad). It is tempting to just turn the heat on low and walk off to do other things; keep an eye on the melting butter and stir occasionally (or more). Add the water, sugar and salt and increase heat to medium. Cook until the mixture registers 260° F (127° C), stirring constantly. This will take about 15 minutes or more. If you don't have a television in the kitchen, you will really give it some thought at this point.

Add 1 cup chopped almonds and stir constantly until 305° F (152° C).
Add the almonds to the hot butter mixture. The temperature will drop, and you can pause worrying about temperature for a little while. The texture of the mixture will go through several phases and get darker. Stir constantly to avoid scorching. Expect another 10 minutes of stirring or more. The final temperature is important, so when you are near the target temperature, you need to really watch it closely. The temperature may continue to rise another degree after you remove the pot from heat, so remove when you are a half degree before target.

Pour hot toffee onto oiled marble board.
Quickly pour the toffee onto the oiled marble board, spreading it as you pour. Don't worry excessively about scraping the pot as the toffee left there can have a strange texture. At this point I will lift one edge of the marble board and tilt it at an extreme angle in order to encourage the toffee blob to spread. I'll tilt it at several angles and directions until I am satisfied. Ultimately you want a consistent thickness, though it will naturally be a little thinner towards the edges. I usually end up with about 1/4 inch thickness. You can use an oiled rolling pin (a marble rolling pin, ideally) to roll the toffee out. I did this for a couple years but it seems to do weird things to the texture and I ended up with butterfat blisters on the surface of the toffee.

Using an oiled carving knife, begin scoring the toffee as it cools.
If you like the jagged, broken look, skip this part, but I like my toffee in small rectangular shapes. Oil the longest, thinnest knife you have with safflower oil. I use a 12 inch carving knife and it works great, but any chef's knife should work. The toffee cools from the outside in, so you will need to make several passes over the same score lines in the center. I usually aim for rectangles that are about 1 x 3 inches. If the knife picks up some toffee, wipe it off with an oiled paper towel. Even if the center is too gooey to have good scores, you still need to tend to the cooler edges. It takes numerous passes to have lines that will persist.

Let the toffee cool. Speed this up by transferring to another surface.
Very warm toffee will not break nicely, so let it cool before trying to break along score lines. If you have another surface you can transfer the toffee to you can slide the toffee there to cool as the marble board will retain heat and slow cooling. Using the knife, carefully separate the toffee from the marble until you can pass the knife under all the toffee. Slide the toffee onto the other surface, being careful not to bend the toffee. I transfer the toffee to an oiled plastic pastry board, but you could also just move it to a cool spot on marble counters (it is probably harder to slide the knife underneath all sides with marble countertop—this is where the raised marble board is nice). If you are using silpat, then you can just keep moving the mat around to cool spots on your counter.

Break cooled toffee along score lines and store between wax paper in an airtight container.
Slide the toffee sheet to the edge of your work surface until a score line is aligned with the edge. Apply gentle pressure with both hands across overhanging toffee and you should get a clean break. You can rotate the piece at right angles to keep the smallest side of the rectangle on the overhang. Place pieces between wax paper and store in an airtight container until ready to dip. I wouldn't store them for more than a day like this, and definitely minimize their exposure to air since most sugar-based candies are hygroscopic.

Prepare jelly roll pans with chopped almonds.
You don't really use all the almonds called for in this recipe, but you will need them to line the jelly roll pans and to facilitate coating chocolate enrobed toffee. Lay a drop cloth on your counter or workspace and set up your chocolate enrobing and almond coating workstation. Toffee will go from dipping to laying in a bed of chopped almonds before having more almonds drizzled on top. It can get messy.

Temper your favorite chocolate.
See the related technique on tempering chocolate for how and why to temper your chocolate. Since you are coating your toffee with almonds over the chocolate, you can actually be a little sloppy with the tempering, but with poorly tempered chocolate the almond coated toffee will need to cool much longer in the almond-lined jelly roll pan before they can be stacked or handled roughly. I have too much candy to make, so I just use a tempering machine rather than fret over chocolate tempering.

Dip the pieces of toffee and lay them in chopped almonds. Coat tops with almonds.
Dip the toffee pieces in your tempered chocolate and transfer to the waiting bed of chopped almonds. I'll usually lay 3 or 4 pieces down on the almonds before grabbing a handful of almonds and gently drizzling the almonds over the pieces in the same order they came out. You should drizzle the almonds on the pieces just before the chocolate sheen goes satin and the chocolate sets. Too soon and the almonds will pull drag the chocolate off the sides of the pieces. Repeat until the jelly roll pan is full. You can then transfer the jelly roll pan to the fridge or a cold room. If you went overboard on the almond chopping, you should have plenty to line another jelly roll pan with, otherwise you must wait for the other toffee to harden enough to permit transfer to another location—an airtight container, ideally.

Store in airtight container at a cool temperature. Storing in the refrigerator is not necessary unless you really want to store it for one or two months. Freshness is key, so consume within 2 weeks for the best taste experience.
