Even lump crabmeat hides shell fragments. Spread it on the paper towel and check with your fingers while you pat the surface moisture off. Wet crab is what turns the salad watery.
Ripe but firm is on the ingredient list for a reason. Press near the stem end; you want a little yield, not a squish. Overripe halves collapse under the weight of the salad.
Stir the crab in last and stop as soon as the dressing coats it. Broken lumps mean the texture is gone, and the texture is most of what lump crab offers.
Rubbing the cut faces with the lemon half slows browning but does not stop it. Score and fill within a few minutes, and get everything on the table inside half an hour.
Mayo and Old Bay brands differ in salt. Taste the dressing on a scrap of celery before it goes near the crab, since you cannot fix it after folding.
Set the six filled halves on plates within thirty minutes of scoring them, while the flesh is still bright green. Three avocados make six boats from one batch of salad, and the dish comes to 5 net carbs per serving. Everything it needs is already in the mix, from the chives to the Old Bay, so the table wants nothing else. Cold plates buy the green flesh a few extra minutes; slide them into the freezer while you fold the salad.
The salad itself keeps 3 to 4 days in a covered container in the fridge and still tastes right on day two. The avocado is a different story. Once cut, it browns past the point of looking good within hours, lemon rub or not, so fill only the halves you are eating and store the two parts separately. Freezing is not worth it here. The mayo breaks when it thaws and the avocado turns watery, and there is no fixing either one.
Yes, up to a day in advance. Keep it covered in the fridge and fill the avocados right before serving. The wait actually helps the Old Bay settle into the dressing.
It will, with one adjustment. Drain it well and pat it drier than you think it needs, since canned meat carries more water than fresh lump crab.
Ripe but firm, as the ingredient list says. The flesh should give to gentle pressure near the stem while the rest stays tight enough to hold its shape when scored.
Cut avocado oxidizes fast, and the lemon rub slows that rather than preventing it. Score, fill, and serve inside thirty minutes, as the method says, and the color stays bright.
You can, but season harder somewhere else. Extra salt and a bigger squeeze of lemon gets you close, though the dressing will taste plainer.
