In a medium saute pan, add the butter and heat to medium heat. Saute the shrimp and garlic until done. It will take just a minute or two.
Remove shrimp to cool.
Now in a medium size bowl, add the shrimp with the cream cheese (room temp), brandy, Worcestershire, hot sauce, seasoning, and fresh dill and mix will. Cover and chill in the refrigerator for several hours. (2 or more to get all the flavors mixed).
Toast the bread (I like a little olive oil drizzled on it). Golden brown. Just takes 2 minutes per side in a 425F oven.
Lightly toss the shrimp mix with the crab and scallions and spread on the warm bread.
That just as an open face sandwich is just perfect to me. A nice bowl of soup and can't get much better.
Or just just put on a hot griddle, grill or saute pan for just 2-3 minutes to heat up and press down and just as good. Either way, it is a great sandwich.
