Start by washing the beef thoroughly to remove any dirt or impurities.
Cut the beef into thin, long strips. You can remove any excess fat if desired.
Season the beef strips with salt, chili powder, garlic powder, and onion powder. You can adjust the amount of seasoning according to your taste preferences.
Place the seasoned beef strips on a drying rack or hang them in a well-ventilated area. Allow them to dry for several hours or until they become dry and crispy. This drying process can take a day or two, depending on the weather conditions.
Once the beef strips are completely dried, heat some vegetable oil in a frying pan or deep fryer.
Fry the dried beef strips in the hot oil until they become golden brown and crispy. Make sure to fry them in small batches to ensure even cooking.
Remove the fried beef strips from the oil and place them on a paper towel to drain any excess oil.
Allow the dambu nama to cool down completely before serving.
