Burong Mustasa or Pickled Flat Mustard Greens is a type of Filipino fermented appetizer wherein flat leaf mustard greens are soaked in a brine solution composed of sea salt and rice water. The latter is the liquid produced after boiling white rice in water.
This way of preparing mustard greens might sounds unappealing to some of you. It is totally understandable. In fact, I felt the same way back then when I haven’t tried one yet. I must say that it takes a little bit of getting-used-to or what they call “developing an acquired taste” before you can appreciate it. I even liked it better after learning that pickling mustard greens this way is still healthy because it preserves most of its nutrients.
There are many uses for burong mustasa. Aside from being an appetizer, it can also be used as an ingredient to prepare certain dishes. A good example of this would be sautéed mustard greens with egg wherein chopped pickled mustard greens are sautéed with garlic, onion, and tomato. A piece or two beaten eggs are added towards the end and then sautéed some more until it gets the consistency of scrambled eggs. It also makes a good side dish for fried and grilled fish. I like to have it with either inihaw na dalag (grilled mudfish or murrel) or inihaw na bangus (grilled milk fish). It is also a perfect with fried galunggong and tinapang isda (smoked fish).
The recipe below will show you how I make my burong mustasa. Note that you can always chop the mustard greens if that is your preference. I like to have it whole because I sometime nibble on it while watching TV. This should be good for 3 weeks when properly stored in cool temperature.
