Place des Vosges
Everyone has their own secret ingredient. Katrina Markoff is the founder of Vosges Haut-Chocolat, so you can imagine what goes into all her recipes. They say to not bring your work home, but in this case she can be excused for sprinkling chocolate onto every dish and drink. Honestly, you can never have too much.
If you asked Sarah Cave about her own secret ingredient, she might not tell you. But it's easy enough to discern: style. You can see it in everything that she does, including this story on Katrina's recipes for the September issue of Better Homes and Gardens.
