Jang jorim is a popular Korean side dish (banchan) using mainly beef, hard boiled eggs, green/red chili peppers and soy sauce. Beef, usually brisket, flank or shank, is simmered in a pungent soy broth, optionally with hard-boiled chicken or quail eggs. Green chili peppers or jalapeños can be also added to the mix for some spciy kick to the overall taste.
This side dish is usually eaten alongside with bop (steam rice) and commonly found in lunchboxes, enjoyed by all age groups. However, preparing and cooking jangjorim will require great amount of time and care so if you have access to a local Korean grocery store or supermarket, this side dish can be easily found in the refrigerated banchan section.
