1/2 lb sea beans
1 tbs black sesame seeds, toasted
1 tsp sesame oil
1 tbs mirin
1 tsp rice wine vinegar
Really more of a description than a recipe. Sea beans (also known as glasswort) resemble little branched haricots verts and have the taste of... the sea.
Soak the beans in an excess of water for at least 3 hours. Remove any tough or woody parts at the root. Blanch for three minutes, refresh in ice water, then drain.
Sliver the kumquats, removing any seeds.
Toss the drained beans, kumquat slivers, sesame seeds, and dressing ingredients together, then adjust seasoning (the quantities I give are approximate- I'm a "by eye" sort of cook). Allow to marinate for 10 minutes, then toss again and plate.
