Before I launch into the super delicious fish sauce treacle candy I made, some background.
Last weekend, my friend Max was making golden syrup for a batch of moon cakes she was baking. Well, golden syrup is (apparently) easy to burn 'cause she burned it. Twice. Oops.
Rather than toss the now-solid syrup, I melted the syrup in a double boiler and added butter and
topped it with Maldon salt -- wow -- it was a tasty (if really hard) caramel.
I got to thinking about making candy and decided to make a nut brittle. I didn't have agave nectar or corn syrup so I substituted molasses. Instant treacle!
Topping it with fish sauce is just guiding the lily of a perfectly delightful, somewhat earthy, treacle brittle. Fish sauce adds a funky, salty, umami start to the candy experience and the nuts keep the fish sauce from getting sticky.
A second variation I made uses gray sea salt from Normandy. Both are delicious but I really prefer the fish sauce interpretation.
Two things before I begin.
You will need an accurate thermometer. I prefer a candy thermometer because it clips efficiently on the side of the pot, but an instant read analog thermometer will do (but don't you dare pay $10 for it! Go to a restaurant supply store, they should cost less than $5).
It is a hard brittle (read - teeth can be broken). Adding a small amount of baking soda at the end does aerate the syrup -- and soften the finished product, but it dulls the glossy color
Fish sauce Cashew Treacle Brittle
1.5 c sugar
.5 cup molasses
.5 cup butter plus some additional to grease parchment paper
.25 cup water
1.5 c freshly roasted cashews* (Finely chop 3 Tbsp of cashews to top the fish sauce)
2-4 Tbsp fish sauce (I prefer Red Boat)
.5 teaspoon baking soda
Cut butter into pieces. Set aside. Cover a cookie sheet or sheet tray with parchment paper. Grease the parchment paper with butter.
Heat the sugar, molasses & water in a heavy sauce pot stirring occasionally until the sugar melts. Add the butter and stir. Place a candy thermometer in the hot sugar.
It will take a sold 15 minutes to attain the proper temperature, 270 degrees. Keep an eye on it and stir or swirl every few moments.
Add the nuts as the sugar approaches soft crack, (soft crack, 270 - 290 degrees). Stir firmly.
OPTIONAL: When it reaches temp, remove from heat and stir in 1/2 teaspoon baking soda. This addition adds tiny bubbles to the syrup and softens the final product. I consider it optional as I like hard brittle.
Quickly dump the hot syrup onto the buttered parchment and spread it with a spatula (ideally greased -- if you remember). Immediately sprinkle fish sauce on the hot syrup and top with chopped cashews.
Sidebar -- topping the brittle with fish sauce makes the surface tacky. The chopped cashews absorb the excess fish sauce creating a clean-hands candy.
Variation -- I have also done a version topped with sel gris or gray salt that I picked up in Paris years ago. It's from Normandy.
Cool completely and break up with a knife or your clean, dry hands. Wrap individual pieces in wax paper.
Bon Appetit!

* How to Roast Cashews: toss with a small amount of olive oil or coconut oil. Bake at 350 degrees for 15 minutes. For this recipe, I didn't add salt but I do salt them if I'm roasting them for a snack. Oh, and for snacking, I add a spring of rosemary for the last five minutes that the nuts cook.
