I recently bought some. I'm planning to play around with them in this summers jam making.
I purchased a nutmeg and a rose geranium. (I was tempted by a lemon, but passed and bought lemon verbena instead.)
Very interested in hearing what varieties you like and how you use them in the kitchen!
Note: I've seen sporadic mentions in past threads, but thought a dedicated thread could be a nice resource.
I've not cooked with them, but use them all the time as garnish - fruit salads, tea sandwiches, small pastries, and mixed in with culinary herbs as kitchen table bouquets.
I was thinking about buying some rose geraniums myself. Geranium sugar is an easy way to experiment with the flavor, but based on the scent, I am also thinking about steeping them in vodka to make geranium liqueur.
The best ever: rose geranium jelly. My mom made it, and I have a couple of times. Fabulous with roast pork or roast lamb, and not too shabby on toast. Lovely pinky pale-orange color.
You make it best with lady apples, which can be located late summer. Use a good jelly recipe and put one rose geranium leaf in each jar. Simple and delicious.
I've only made geranium sugar. Herbal jellies are nice in thumbprint cookies. I tend to get too many each spring and never winter them over. Rober's Lemon Rose is one of my favorites but the leaves aren't as pretty - more like a tomato leaf.
