My DD and I just loved this! It was super easy to make a delicious creamy comfort food. I used my blender to puree the mixture of ingredients. Made for Veg "N Swap #19 tag. Thanks for posting!
Gosh - we loved this. Almost like creamed spinach/comfort food, but with the different taste of watercress. I didn/t want to add all that butter, so I added some chicken base to the water when I cooked the potato, and used way less salt. I did use 2 T butter. The recipe didn't say how much water to use, so I used about 1 inch over the potatoes, figuring the watercress would cook down quite a bit, and I was right - this worked well. This was so easy that I will probably make it again, and maybe use the method for other veggies as well. Thanks, Elmotoo, for posting.
