Thanks, Greg! We've used the pickled rose petals as an added ingredient in really any salad. We've also used it on top of chervil pesto over noodles, which was really nice. If you've ever eaten pesto with sundried tomatoes, it takes the place of the tomatoes for that umami element.
^^^ What Greg said above. Also, we used the buds with the stem, outer bud leaf still attached in the pickled rose petals, and it was delicious. My husband has a very sweet-oriented palate, and he loved them. You pickle them with honey and vinegar.
