This listing is for 50 Spiny Sow Thistle (Sonchus asper) seeds Common names include Sharp-fringed Sow Thistle, Prickly Sow Thistle, Spiny Sow Thistle, or Spiny-leaved Sow Thistle. Its edible leaves make a palatable and nutritious leaf vegetable. I collect the sap of this one. FREE RECIPE: BUTTERED SOW-THISTLE 1 or 2 handfuls sow-thistle leaves ? young Butter or oil Beef stock or water Ground nutmeg ? pinch 1 tsp. flour Salt and pepper For this recipe the young 2- to 4-inch leaves of common sow-thistle [Sonchus oleraceus] are best and when the leaves are not bitter. Other sow-thistle species may need their spines trimming off and may be bitter to the taste requiring some preparatory boiling. Heat some butter or oil in a pan and add the leaves. Stir thoroughly to coat the leaves. Add a good slug of stock or water, reduce the heat to a simmer and cover. Cook for about 5 to 10 minutes. Add a pinch of nutmeg, the flour and some seasoning. Stir everything, then add another knob of butter and melt into the sow-thistle over a low heat. Serve. Thank You for Looking!
