How to make
Peel the potatoes and put them to fully boil in salted water along with the cleaned carrots. The water must cover the vegetables in the pot.
Once they are ready, mash everything straight in the pot. If necessary, let it simmer to thicken. Add the butter and egg yolk that you've stirred with the cream with a fork.
Season with salt, black pepper and savory. Serve with croutons if desired.
