Our pumpkin chipotle mash started with this recipe. It veered off this recipe when none of us could figure out what a 1/4 crown pumpkin was. I thought it was some kind of measurement so I asked the boys to google how many ounces in a 1/4 crown. But it isn't - apparently what we call a fairytale pumpkin in Great Britain is called a crown prince pumpkin. But this still doesn't really help because these pumpkins come in sizes from 3 to 20 pounds. Anyway I used equal amounts of potatoes and pumpkin. I also used chipotle chilies in adobo sauce instead of the red chilies. Otherwise, I followed the the directions by frying the onions and adding the cream, then mashing the cooked potatoes and pumpkin with the onions/cream mixture. I also followed the serving suggestion of having it with brisket. It was delicious.
