Tapas - Shrimp and mushrooms in Almond Sauce

Really really great!  Definitely restaurant quality.

Notes:
- Recipe says start a day ahead to marinate overnight.  I marinated for 6 hours and it was fine.
- I used home made fish stock, but I think it would have been totally fine with the clam juice.
- I quartered 4 regular-size mushrooms
- VERY important to use good shrimp that you like the taste of.  (We use TJ Argentinian Red Shrimp ).
