I just made this up last night! Man, I should totally go on Iron Chef.

1 tablespoon extra virgin olive oil
1 teaspoon light soy
juice from 1/2 small lemon
drop or two of sesame oil (careful)
about 6 grinds black pepper
1/2 teaspoon mirin
1/4 teaspoon fish sauce

Shake well in a jar. Best served chilled.

It makes about 1/4 cup. If you don’t have mirin you could probably use some dissolved sugar. I was surprised this actually emulsified; it must be the soy.

It might be nice over cold soba noodles, too. Maybe with double the soy.
