"Like a dream, the puffs were airy and fluffy inside with a nice light crust. The custard cream was just delicious and the perfect consistency. I used a hand mixer when mixing the egg yolks, sugar and flour for the custard cream. I used a makeshift double boiler to cook the custard (I put the pot with the custard slightly submerged in gently boiling water that was in a larger pot I had on the burner), and I omitted the last tablespoon of melted butter. I cooked the puffs on a buttered cookie sheet checking them every few minutes. I put them in at 450 degrees until the tips were golden brown (about 10 minutes) then lowered the heat to 350 until the rest of the puffs became a light golden (about 7 minutes) and then lowered the heat to 250 and cooked them until done (about 5 mins). I found the cooking process was actually a lot less fuss than I had anticipated. I am sure I will make them again soon... considering my little sister said she would like 1 million of them for her birthday in June! Thank you for this recipe!"
