First - pick the flavor of fruit preserves/jam/jelly that you like. I prefer blackberry, peach or apricot for this usually - but no rules. Whatever you like.
Remove the lid, and pop it in the microwave and gently warm it to a pourable state.
Add a SMALL splash of apple cider vinegar - you can add more if needed. Just add enough to make the mixture loose enough that you can squeeze it out thru a typical squeeze top bottle ( like the ones restaurant tables). Add a pinch of salt - it makes adifference...
Now, dust in jalapeno powder or cayenne powder - whichever you prefer. Just enough to create a balance of sweet, tart, spicy that you like.
I like to use this on top of moinks when they come out of the smoker and have cooled just enough to eat.
