Melt the butter in a pan on really low heat. Then add the beaten eggs (no salt or cream added yet!)
Cook on low heat so that the eggs coagulates homogeneously all around. Remove from the heat or lower it if you see that lumps of overcooked egg start to form. Then return to the heat as adequate.
Once cooked (not dry), add the cream and season with salt. Serve warm on toast with ham, avocado, cheese, or anything else you like.
Finish with seeds of your choice. I used sunflower and black sesame seeds.
