I always use honey, never sugar. I sauté chopped garlic in a bit of olive oil. Add the peanut butter, honey, coconut milk. You could stop there and have a very basic peanut sauce. I like to add red pepper flakes, sliced green onion, and a drizzle of chili oil.
I'm not convinced this will freeze, though. The fat content may be too high.
How can we sleep while our beds are burning???
