I’m going to say something heretical. But mint is very expensive here. (I just need to plant some) but when I can’t get it, mint bitters or syrup can give similar flavor. My southern card is going to get taken away.
It's like a weed if you'll borrow a couple of plants with roots & stick them in nice soil. It spreads and comes back each year. Julips, mojitos, tikis, bourbon smashes etc require fresh FREE spearmint.
