I heard a question on a quiz show this week about George Washington Carver

"Carver's inventions include hundreds of products, including more than 300 from peanuts (milk, plastics, paints, dyes, cosmetics, medicinal oils, soap, ink, wood stains)" but he didn't invent peanut butter.

Senoufou, your husband's curry combined with pb makes sense to me.

This is one of the many variations on a recipe for satay sauce:

Ingredients

    1 cup fresh dry roasted peanuts (unsalted)
    1/3 cup water
    1 to 2 cloves garlic (minced)
    1/2 teaspoon dark soy sauce
    2 teaspoon sesame oil
    2 tablespoons brown sugar
    1 to 2 tablespoons fish sauce (depending on desired saltiness/flavor; vegetarians substitute 1 1/2 to 2 1/2 tablespoons regular soy sauce)
    1/2 teaspoon tamarind paste (or 1/2 tablespoon lime juice)
    1/2 teaspoon cayenne pepper (or 1 teaspoon Thai chili sauce; more or less, to taste)
    1/3 cup coconut milk
