In a seperate bowl, combine all of your ingrediants. Mix well and then taste. Ketchup is a great base, as it is sweet a tangy. Let your taste buds tell you if you need something optional. If you like it sweet, add the pinapple. If you want it spicy, add 1 tablespoon of sriacha, etc. Plese add in small ammounts. You can always add more, but too much and you have to do a lot of manipulation to get what you want.
