I have an abundance of mint that I'd like to use to make mint syrup. The plants are mildly infested with aphids, but that hasn't stopped them from thriving. If I harvest the mint, what can I do to wash off the aphids so I can boil it down to make delicious syrup, and subsequently, delicious mint juleps?
Just wash them off with a jet of water. They will come off easily. If you have already cut the mint shake them off and rinse off in the sink. Before using the mint check thoroughly. They should be gone and the boiling will make sure that nothing survives. Good luck.
If you eat frozen broccoli, you've probably already eaten aphids. (That document lists the presence of aphids as "Aesthetic", so the presence of a few doesn't sound too harmful anyway.)
Just rinse well and give it an inspection. You're going to boil the daylights out of it and then use bourbon as a "sterilizing agent" anyway :)
