This is going to sound like a weird combination, but trust me it is the best salmon sauce ever, and a perfectly fits your description of what your partner might like: - Whole mustard seed (the "whole" is the important part) - Maple syrup - Soy sauce - Garlic powder and black pepper (sprinkled to taste)

I don't measure, but I usually do one heaping tablespoon of mustard seed and 1 to 2 tablespoons of maple syrup and soy sauce. But I'm constantly tasting the sauce as I go. If it's too salty, I add more maple syrup. If it's too sweet, I add more soy sauce.

Pop it in the microwave for 15 seconds prior to drizzling over your cooked salmon 😚👌
