Last weekend's Sheffield Food Festival thrilled with fresh delights. Invited to cruise through the stalls on local radio with Rob, the charming (and surprisingly very tall) winner of The Big Allotment Challenge, I discovered the delights of the black carrot. This somber veg is apparently an original hue of our familiar orange variety, allegedly then cultivated to match the Dutch flag. Actually more purple than black, I chomped on this tasty root and committed to come up with a recipe for my regular slot on Radio Sheffield. Picking up some wonderful cheeses along the way, including a vintage 3-year-old called Knuckleduster, I also discovered a delicious wild garlic pesto. This ramson-rich relish was so captivating that I managed to mention it three times in 15 minutes! So this week's culinary offering was a black carrot and Knuckleduster tartlet with wild garlic pesto (there, I've said it again), which is now in the recipes section. And what next for the black carrot? Well, I'm picturing a carrot cake fit for Donnie Darko. Hop over to the dark side Bugs.
