Bring a large pot of water to a boil over high heat.
Clean and cut turnips into roughly equal-size pieces. Here are a few tips about preparing turnips, rutabagas and parsnips.
Add turnips to boil water and reduce heat to medium. Boil until tender (about 30 minutes).
Drain and mash turnips.
Add onions to mashed turnips. Add salt, sugar, pepper, and cayenne. Mix well.
In a small bowl beat egg yolks, add them to the turnip mixture, and stir gently until just combined.
In a medium bowl, whisk the egg whites until stiff peaks form. Then, gently fold the egg whites into the mashed turnip mixture.
Put turnip mixture in the greased casserole dish and bake 20-25 minutes.
