I'd like to make a rose petal jam, which requires roughly 14-16 ounces of rose petals. However, I've been warned to not buy roses from florists, due to potential pesticide issues from roses sold for being displayed, not for eating. Is there any place to get fresh rose petals that are organic and/or pesticide free? My guess would be a farmer's market or the like?
You can try organic markets in your area
This is a crap-shoot, but if you have any gardeners who grow roses in your neighborhood it might be worth it to ask around and see if you could buy or barter for some of their flowers. You could also grow your own.
Alternatively, see if there is an organic florist in your area. Interest in organic goods is increasing in North America, and people are getting into this market.
Very difficult. I don't think there is a place at this time. I have made wonderful rose jelly but you will not get the flavor you are looking for if they are not plucked straight away from the rose bush. Wild roses often do not have the fragrance, which is where the flavor will derive from. When you find, it is best to pick in the morning. Pull petals off and snip the white base as it is bitter. Best bet is to find an organic, non-pesticide farmer/gardener or grow yourself.
