I tried a modification of David Thompson's mi krop recipe (basically, I added pork, shrimp, chicken and tofu as his recipe does not include any protein).
His recipe includes a lot of Thai yellow bean sauce (dao jiao-I cup!), which gets pureed, eggs to thicken the sauce, and a lot of sugar (also 1 cup). I have to say. I liked my last batch better. This recipe was just O.k. (one of the few from Thompson's cookbooks I didn't think was at least very good). I couldn't find sour orange (they didn't have it at Fresh Farms this trip) so I used Thompson's suggestion of mandarin and lime juices and I did really like the flavor from the mandarin. I've been making Mi Krob for a looong time (it was one of the first Thai dishes I made in college) and I have to say that riffs on my old, battered
1986 cookbook by Pojanee Vatanapan turn out the best. I think my next batch will be based on this cookbook with the addition of either sour orange or mandarin/lime juice.
