Making homemade tamales is quite an undertaking. These little bites give you that same combination of soft, steamy masa dough and rich filling. To shave off even more time, use cooked chorizo instead of making a pork filling. Masa harina is fresh corn dough that's been dried and ground into flour. Find it in the international aisle of your grocery store or at Latino markets. For the best flavor and lightest texture, get fresh lard (rather than shelf-stable hydrogenated lard) from a butcher shop or a Latino market.
