You can buy beef tripe at most grocery stores. I prefer to use Rumba Meats. u003cbr/u003eu003cbr/u003eThanks to Rumba Meats, my abuela's Mondongo recipe turned out perfect! Rumba Meats gives you the fresh, high-quality traditional variety meats to share your u003cemu003epasión y vitalidadu003c/emu003e with the u003cemu003eamigos y familiau003c/emu003e who bring your worlds together. Its products are vacuum-sealed for added freshness. By vacuum-sealing all cuts of Rumba Meats, its products stay fresher longer in your refrigerator (28 days for most products; 25 for hind shank) until you’re ready to use them.u003cbr/u003eu003cbr/u003eVisit the u003ca href=u0022https://rumbameats.comu0022 target=u0022_blanku0022 rel=u0022noreferrer noopeneru0022u003eRumba Meats websiteu003c/au003e for more delicious recipes and to learn more about its wide variety of quality specialty beef cuts – nearly 20 in total!
