Funfetti Cookie Recipe : Strange after taste, why?
Used this recipe, first time baking anything from this website too : http://sallysbakingaddiction.com/2013/04/26/soft-baked-funfetti-sugar-cookies/
I'm an amateur baker, but I think I'm pretty good at following directions. Haven't had major issues baking before. I followed the directions, let the dough rest over night, portioned it out to half-tablespoon sized, and froze all but 5 of them. Baked off those 5 cookies (reduced the time to 5-6 min since my cookies were much smaller). Texture and bake came out well, exactly like what the recipe said. Lightly golden brown undersides, soft baked interior as promised.
But... there is a really off, metallic after taste that I've never gotten from any of my cookie bakes before. I'm wondering why? Is it a recipe issue? I've never used cream of tartar in any of my cookie or bar recipes before, so that was a first for me. Or could it be my sprinkles are old/off? I kind of doubt that unless sprinkles really do expire, since I used these same sprinkles to make the Smitten Kitchen confetti cookie just earlier in December for a dinner party, and those tasted great.
I still have that aftertaste in my mouth :(
