Miracle fruit is a little red berry from Africa, originally eaten by the local populace to make their food taste better, but now also a staple in the diets of urban foodies and inquisitive geeks elsewhere in the world. The berry itself doesn’t taste like much–or so I’ve heard, as I’ve never had a fresh one–but the results are, well, miraculous, thanks to a chemical in the berry called–get this–”miraculin”. When scientists start calling things miracles, you know you’re dealing with something truly special.
