I love making this salad! However, I hate recipes that just say - two apples, or three onions - tell me how much! And this recipe calls for 2 shallots, which can vary greatly in size and have a bit of a sharp edge when raw. So when I made it last night, I measured out 1/4 of a cup of chopped shallots and it was perfect. It's more or less one medium shallot. Oh, and I don't bother with all the smoking and such - my husband just grilled the salmon like he always does.
