It would be too bad if salted caramels became, as it were, a victim of their own success. American tastes have always run to the salt-tinged sweet; we just never identified it in a way that could deem it faddish. Chocolate covered pretzels, tin roof sundaes, gritty Reece's peanut butter cups, cracker jacks, pay day bars- salt keeps sweets lively and balanced. Fashion aside, salted caramels are one of our confectionery staples. They glitter with flaky salt scraped off of rocks in the sea in Crete and the other ingredients are just cream and butter and sugar, and a shot of rum, marrying the flavors and giving a subtle base note. These are a satisfying project- turning a liquid into a dense creamy solid with a gently yielding chew feels like magic. They have a bold luscious dairy richness, and that bite of salt is fresh like the sea air.
Just because making candy is like magic does not mean it is difficult- a candy thermometer makes these very simple. (However, growing up without a candy thermometer and using instead glasses of ice water lined up on the counter to test the consistency brought me closer to the secret life of things).
We will need:
600 g/ 3 C sugar
120 g/ 1/2 C corn syrup
120 ml/ 1/2 C water
1 tsp flaky sea salt
400 ml/ scant 2 C heavy cream
140 g/ 5 oz butter
1 shot rum, or some vanilla
Before starting to cook, line a loaf pan with foil and butter it thickly and thoroughly. Get our a candy thermometer and put it in a glass of hot water.
Heat the cream, butter, and salt together in a small pan.
Take a large, tall pan (the mixture will bubble up like mad when we add the cream to the caramel), pour the sugar into the center, the water around it, and the corn syrup over the whole. Warm, then let it come to a full boil- it will be frothy and white-
Keep a watching it- don't leave the stove for a second. It will stay white, and white, and white, then. as soon as it starts to take on some color, it darkens quickly. When it is a deep honey color, stand back as far as you can and pour in the hot cream. It froths and steams like a volcano and is really loud.
As soon as it subsides, give it a few stirs with a long-handled wooden spoon, attach a candy thermometer, and again keep the closest watch. The thermometer climbs slowly at first and then picks up speed.
The very second it reaches 115 C/ 240 F, take it from the heat, add the rum, and pout it into the waiting pan lined with buttered foil. Sprinkle lightly with more sea salt. Let it cool at room temperature- which takes forever or at least 5 - 6 hours, or put it outside, as I did. It's winter, and the cold caramel gets really hard and you'll think, at least I did, that it is overcooked it and it would be too hard and chewy. As it comes to room temperature and also seems to take in some softening moisture from the air, it is firm enough to hold its shape, soft enough to melt on the tongue.
Turn the bar out upside down onto a piece of non-stick baking paper. Carefully peel off the foil and, while still upside down, but it into whatever size pieces you like (cutting through the softer underside makes neat pieces).
Finishing-
They are ready to eat and delicious plain, but hard to wrap or serve or give- you cannot trust the surface to not stick to anything after a few hours. An elegant solution is to dip the bottoms only in tempered chocolate. Also, the salt has sunk in and you can't see it so well- a few streaks of chocolate on top give the more salt something to cling to and shimmer.
Take a little over half of 200 g/ 7 oz. dark chocolate, melt it in the microwave or over simmering water, then add the rest of the chocolate. Stir until it melts in and the temperature of the chocolate cools (it will feel cool to your bottom lip). Dip the bottoms of the caramels, letting it come up the sides as much as you like, set them on a piece of non-stick paper, and drizzle the rest over the tops, sprinkling with salt flakes right away before it has a chance to set (tempered chocolate sets fast).
