While your satay is baking you can make the quick satay sauce, it only takes a few minutes.
In a small pot, heat a little oil, sauté the onion and garlic until softened and fragrant. If you know that you will want a little chilli heat in your satay sauce you can add the chilli flakes to the onion and garlic, you get a little nicer flavour if you do this. (I add mine later, as I often remove some of the sauce before adding the chilli so that my non-chilli liking kid will still have some satay sauce to enjoy)
Add the peanut butter, coconut cream, and water, stir until melted, combined, and smooth. (photo 2).
Add the soy sauce, and lime or lemon juice, stir through. Taste, if you haven't added chilli and you wish to, you can add it now.
Set aside to serve with the satay tofu. I often prepare this sauce in advance and serve it cold with my tofu.
