Massaman Beef Curry with Potatoes and Pineapple

Just in case you were wondering what the heck I did with all that fabulous curry paste I made, here it is.  True Thai has two Massaman curry recipies, and while I've made the vegetarian one (Massaman Curry with Sweet Potato, Fried Tofu Squares and Peanuts) several times, I had never made this one, until now.

It is both easy and yummy, and I highly recommend it, except that the recipe as written has probably a bit too much tamarind for my taste.  Next time I might try adding only a tablespoon of the tamarind concentrate, and then adding more if it needs more sour.
