Hi! I am Mexican, and also a chef. Purslane is a common herb in traditional mexican cuisine. Almost every ethnic mexican store that carries fresh vegetables will carry it. Purslane is known by its high content in iron, which is higher than in spinach.
A common way to eat it is in a dish called "cerdo con verdolagas" (pork with purslane). It is made by making a green sauce with tomatillos, and then adding cooked and fried pieces of pork, and lots of purslane stems. All this is simmered until the purslane its cooked. I have made my US colleagues tried it and they loved it!! They would hardly believe that they were eating what in here, the US, is considered "a weed".
Where to Buy: USA
Hello, This is Merryanne in Central FL,,I just found Purslane for sale in my neighborhood,,I went to an open air market, it is always there on Saturday and Sunday,but I had not been to it in several years, well I was looking at the Mexican tables of produce and was schocked!!! There lay stacks of bundled purslane for $1.75, I was shocked,,I have spent a lot of time online looking for it and it is in my own neighborhood,,,If anyone is looking for it try you spanish stores, especilly the Mexican stores,,The man there said it is farmed just like there other crops. So I am going to start eating it and learn to make smothies.
