• Greens from several radishes (enough to overfill the frying pan)
• 1 small onion
• ~2 tbsp butter
• ~1/4 cup cream
• ~3tbsp lemon juice
• ~1/4 cup of water or broth

Saute the onion in butter for ~2 min (no browning), add some salt and pepper.

Add the greens, saute until welted, ~3min

Add the lemon juice and add enough water so that it takes a good 15min to reduce and the greens soften up. Add some more salt and pepper.

Once there is only a little water left and the green have simmered for at least 15min, add the cream, let it reduce until the right thickness.
