I use Indonesian tofu. It's sometimes soaked in turmeric so the color is yellow. I think this one is tastier, but you can use any kind of firm tofu. Pat dry the tofu with tissue paper or towel.
Slice the tofu into triangles. Adjust the size to your preference.
Carefully make a hole in the tofu.
In the mean time, mix ground beef and other ingredients (except oil) and knead it for a couple of minutes. Add the small part of tofu from step 3 into this and mix well.
Take some meat mixture and carefully insert some to the tofu, making sure the meat is firm enough.
Fry in hot oil and flip after the tofu has turned golden brown. Traditionally, we eat this with bird's eye chili but this time I used a mixture of mayo, hot sauce, a bit sugar, and lime.
