Does anyone know where I can buy high quality lard in Dallas?
I would try the Fiesta markets, Rudolphs Meat Market and possibly, 99 Ranch Market in Plano for starters.
Walmart Supercenter or Neighborhood Grocery. Look in the Hispanic food section (Manteca de Cerdo.) It's a fairly popular product so it is almost always very fresh. Check the date on the carton. If you want leaf lard or other "gourmet" stuff, maybe soemplace like Central Market would have it in stock or could get it for you. La Michoacana might have it, too.
It depends on what type of lard you're looking for. There's the kind that's like Crisco that's white and solid and sold in sticks or tubs, often used for tortilla-making. That kind you can get at Wal-Mart or the grocery store in the Hispanic food section. If you want the type that's good for making tamales, the tub of runny, tan color lard that has a bit of pork smell to it, look at Fiesta, Carnaval, or pretty much any Hispanic market. If you're looking for specialty lard, such as the lacy leaf lard used for baking, I've seen it on Livestock First Ranch's board (in limited quantities) at the Coppell Farmers Market, and I'm sure many of our other local ranchers sell it at farmers markets.
