Tripe soup, especially when served with garlic and vinegar in cold weather, is a beloved dish. However, cleaning the tripe before making the soup is a laborious step that intimidates many people, so some choose to avoid tripe rather than clean it themselves. In fact, when done in the right order, cleaning tripe is easier and more practical than it may seem; you just need to follow a few steps. The steps below explain what to do, from the initial cleaning through the final rinse.
Initial Cleaning and Rubbing with Salt
For the initial cleaning, rinse the tripe under cold running water at least 5 to 6 times to remove coarse dirt and debris. Work in a deep bowl or sink without splashing, and when you finish, wash the sink and surrounding surfaces with hot, soapy water and sanitize them. Wearing gloves during this step and the steps that follow improves hygiene and helps keep the odor from lingering on your hands.
After the initial cleaning, rub both sides of the tripe with rock salt. The salt crystals help remove much of the dirt and odor stuck to the surface. Continue rubbing for a few minutes, then rinse again with plenty of water.
Scraping with a Knife
Carefully scrape the tripe, after the initial cleaning, with a knife. This is the most important part of cleaning because it removes the thin membrane left on the inside surface. Work neatly and patiently; do not rush.
As you scrape, check each part of the tripe individually so that no area is missed; spots that have not been scraped thoroughly can negatively affect the soup’s odor. When scraping is complete, wash the tripe again with plenty of water.
Soaking in Vinegar Water
First rinse the scraped tripe with warm water, then soak it in water with white vinegar added. If you do not have white vinegar at home, apple cider or grape vinegar can be used for the same purpose. Vinegar is said to help remove much of the residue and odor from the tripe.
It is recommended to soak the tripe in water with vinegar for 5 to 10 minutes; this helps reduce the odor and soften the texture somewhat. You can extend the soaking time, but adjust it carefully so the tripe does not become too soft.
Final Step in Boiling Water
Briefly dip the tripe that has been soaked in water with vinegar into a pot of boiling water with one or two 15 ml measures of baking soda added, then remove it. The hot water helps bring any remaining dirt inside the tripe to the surface. Scrape the removed tripe once more with a knife to finish cleaning it.
The most important thing at this stage is not to leave the tripe in boiling water for too long; otherwise, it will cook and become firm, making it harder to clean. Brief, controlled dips avoid this risk.
Final Rinse and Next Steps
After completing all the cleaning steps, rinse the tripe one final time with warm water. By this point, most of the odor should be gone and the surface should feel smooth. The tripe is then ready to slice.
You can add the sliced tripe directly to the soup or, depending on the recipe, boil it first and use it afterward. Following each cleaning step carefully can noticeably improve the soup’s odor and texture.
Common Mistakes When Cleaning Tripe
One of the most common mistakes is rinsing the tripe with cold water only 1 time and then starting to cook it. Inadequate initial cleaning can leave an unwanted odor in the soup. Skipping the salt-rubbing step can have a similar result, since the rock salt removes much of the dirt on the surface.
Leaving the tripe in boiling water longer than necessary is another common mistake that can make its texture firm; this step must be brief and controlled. Skipping the vinegar-water soak can also leave some odor behind, so it is recommended not to skip any steps.
