Having preserved herbs on hand is probably my favorite trick for everything I make. Most herbs have one particular method of preserving which suits them best, either drying, preserving in oil, freezing in oil, or preserving in apple cider vinegar.
Once you've eaten as much fresh pesto as you can stomach and have given away enough dill, marjoram, and thyme to outfit a small herbarium, it’s time to consider plan B: freezing and drying those herbs for later use.
This recipe is a tad intense to prep. But all the fuss is forgotten when the heat hits the pot — the perfume of the lemons and lovely pink hue that the onions bring to the picture dispel all memory of tedium. This is truly a gorgeous jam.
