{"type":"firestarter.listing","listing":{"id":"lst_6bjjuKjo","product_name":"Amish Paste Tomato","category":"Vegetables","description":"A consistently great sauce variety. This heirloom is technically a plum, but of the larger sort. Plump, elongated fruit with broad shoulders, and dense meaty flesh. The juicy texture makes a thin sauce--cook down for a thicker, super-sweet sauce. A great variety to slice in half, then roast, peel and add to soups, sauces or top a pizza with. One of our all-time favorites!\n\nAmish Paste is part of Slow Foods US Ark of Taste, a catalog of over 200 delicious foods in danger of extinction. By promoting, sowing, and growing Ark products we help ensure they remain in production and on our plates.
