I have a HUGE bowl of currants, and only 1 currant recipe: jelly.  I don't have any pectin right now, so I figured hey, I'll substitute currants, for blueberries, and make muffins.

LOL... bad idea.  These little things are so sour, Jessica said "mom these are really good, but super sour, I think my brain is doing the skitchies".

Cooking lesson #421: never substitute currants for blueberries in your muffin recipe.
