Make a loose puree with egg, potatoes, butter, pepper and salt. Pipe small heaps onto a greased baking tray and brown the tops slightly in the oven heated to 200 degrees.
For the vegetable sauce, dice the tomatoes and onion. Simmer everything in a small saucepan for 10 minutes. Add the paradeis pulp and strain the cooked amount through a sieve.
Serve the potato stars with the hot paradeis sauce and bring to the table hot on the spot.
