I was wandering around the Farmer's market this morning, and I spotted a selection of different mints at one of the stands. They had spearmint, chocolate mint, and bergamont mint. After tasting and smelling each of them I grabbed the chocolate mint with a julep in mind. Normally I just use the generic chinese market mint up the street, so this was the first experimentation part: novel mint. I needed lemons and limes, and being in Northern California I don't exactly see great variants of that at the farmer's market for the most part, so I stopped by the little produce market on my way home. While i was there getting my lemons and limes I saw panela, and thought I would make aqua panela with it. So I get home, and start the fun process of picking a small solid block of ice I keep in a sandwich container in the freezer for just this occasion. Takes quite a while, I need to come up with a better crushing solution, but that's another story. Basically I muddled the chocolate mint with panela, instead of plain sugar like I usually use, addded the ice and bourbon, into my julep cup, and got the cone effect going on. I'm just sipping on it now, and I thought the idea of subtle variations on a theme was an interesting one. If you put a bunch of extra stuff in it, it's not really a mint julep anymore, but if you tweak the ingredients slightly what interesting things can you do? I've considered making a thai basil julep before once or twice as well. Here's my bad cellphone picture. I'm holding the plate up while taking it, which is why it's a little off. What other subtle variations have people tried and enjoyed in their cocktails?
