I added pork instead of chicken and cut out the tofu entirely. I changed up the recipe quite a bit but I wanted to post my pic. I also used palm sugar instead of regular sugar. I am so glad there is no ketchup involved. Tamarind pulp is easy to find and you can freeze the sauce separately and save it for later. It takes a long time to get thick and syrupy when you make a big batch but it's worth it.
