If you are new to visiting a farmers market, my advice is to keep it simple. Don’t overbuy! it is really easy to do, especially if you go without a plan. The saddest thing is seeing what you’ve purchased go to waste because you couldn’t go through it all. Start conservatively.
Be conservative with “eat-immediately” items- things that will not last very long – like sprouts, lettuce, berries, some fruits. Opt for 1-2.
Be less conservative with produce that keeps for longer (potatoes, apples, cabbages, winter squashes, leeks, kale, etc) that give you more time to consume them. Buy more of these.
Try one new thing. Just one. ( I like to go with a plan in mind of what I need for the week, and then just surprise myself at the market with one more beautiful thing- just one!)
Buy potted herbs! The best tip here! I often buy specialty items like Thai basil, garlic chives, purple basil- thing’s I can’t readily find at the grocery store.
