The first time I ate shishito peppers was in Spain at a tapas bar. I was blown away with the simplicity of the dish, yet how impressed the group was by it. 1 in 5 or so shishito peppers are very spicy and the rest are quite mild. This turns the dish into a game of roulette. But the entertainment factor isn't the only thing going for this dish. The salt and spiciness of the peppers mixed with the spice and sweetness of the aioli is quite delicious. There won't be a single pepper left on the plate, I guarantee it.
