I can manage Yorkshire puddings if I make them with lots of eggs, bread flour and cream diluted with water - the family say that they are better than my mother's recipe which is quite something.
I avoid potato though - I use swede, turnip, cauliflower, any low carb vege as an alternative. Swede, boiled then baked and mashed is slightly more fiddly than potato, but it seems worth the extra effort when on the fork.
