Mhays is right, "guiso" is a stew and "guisado" means stewed. I emailed my friend Nance (of the Klehm variety, she of urban foraging and Little Village orchardista fame) to see if she's ever drank/prepared anything with alfalfa here or in her travels to Mexico. I must say, I totally associate alfalfa with horses and hippy sprouts that taste like hair in your sandwich/salad, so this is such a happy new discovery. I like wheat grass in moderation for its grassiness and sweetness.
Last year at this time I bought purslane, a succulent known as "verdolaga" at a Pete's Market near Midway. I'd eaten a lovely, simple version of it at Los Nopales and then noticed that it was growing in many cracks in the city sidewalks. The Pete's version (not the sidewalk version) steamed up nicely and was also a good addition to salads. It kept in my fridge for weeks. It's supposed to be a great source of Vitamin C and good for your heart.
Anyhow, if anyone knows about the health benefits associated with alfalfa, I'd love to hear them. And how fleeting is the window for buying alfalfa in any form at a restaurant?
buen provecho.
