Sounds yummy, the soy sauce is an interesting addition.
My son started us making caramels this year, using the recipe below that we adapted. For Christmas we replaced half the corn syrup with maple syrup and
honey:
CHARLIE’S CARAMELS
(Adapted from ”Vegan Food for the Rest of Us” by Ann Hodgman)
Start this recipe at least 8 hours before you want to eat the caramels.
2 Tbsp Coconut oil
One 13 oz can full-fat coconut
milk (Chaokoh brand, if available)
3/4 cup light corn syrup
1/2
tsp salt
1 3/4 cup white sugar
3/4 cup
water
1 tsp vanilla extract
1 cup toasted chopped pecans
Grease a square glass baking dish with coconut oil. Spread pecans out evenly. Set aside.
Heat coconut milk, 1/2 cup of the corn syrup, and salt until just warmed through and stir to dissolve any lumps. Set aside. (may sub honey or maple syrup here)
Grease the inside of a large (at least 8 qt) non-reactive pot. Add the sugar, 1/4 cup of corn syrup and water. Cook stirring over medium high heat until mixture reaches a boil.
Stop stirring and reduce heat to medium-low. Watch the mixture. During this phase, you may gently stir in any crystals that form at the edges, otherwise let the mixture be. Cook until the mixture turns light amber and candy thermometer reads 310º F.
Remove the pot from heat and—being careful to avoid spatters—pour in the coconut milk mixture.
Return the pot to the store and stir over medium-low until lumps are dissolved. Raise heat to medium and cook stirring constantly until the thermometer reads 240º F. This could take 45 minutes or more.
Remove from heat. Stir in vanilla. Pour into the prepared pan. Let cool 6 hours or overnight.
Using a straight-edged metal spatula, cut the caramel into one-inch strips, and then cut each strip into bite-sized pieces and wrap in waxed paper.
