I made this a couple of months ago. I didn’t have the proper noodles, but had the ingredients for the sauce. It was perfect with rice as well so it was 성공 (success)! I followed this jjajangbap sauce recipe from your video on YouTube!
Which to get? my first book has all the recipes for all the essential Korean pastes and sauces, but my second book Maangchi's Big Book of Korean Cooking has more recipes. Both are best sellers and either one is a good choice if you want to learn Korean home cooking.
