1. It's made of whitefish.
2. It's firm, sweet, and buttery.
3. Mock lobster and crab are interchangeable.
I used cod, I suppose you could use just about any mild white fish. I used a little food coloring to give it 'the look':
It's not exactly the same, but it's great for recipes like crab rangoon or lobster mac n' cheese. You could probably even mix it with some mayo and throw it on a bun for a makeshift lobster roll.
Mock Imitation Crab
1/4 cup water
1 Tbsp sugar
1 tsp salt
1 Tbsp melted butter
1 Tbsp vinegar
3-5 drops red food coloring
Combine water, sugar, salt, butter, vinegar, and food coloring in a small baking dish. You should have enough liquid to cover the bottom of the dish, adjust as needed. Place fish in dish and cover. Bake at 300 for 45 minutes, 60 if frozen. Do not flip at any time -- you want the pink-to-white gradient.
Transfer the cooked fish to a plate, discard liquid and allow fish to cool. Flake it with your hands into desired pieces.
