HOW TO
place each egg yolks in a small cup
mix the sugar and salt (equal parts, e.g. 200g salt and 200g sugar)
fill approx. 2/3 of the mix into the casserole dish
make little pits in the sugar/salt-mix and carefully slide your egg yolks into them (the yolks should not touch each other)
cover well with the last third of the sugar/salt-mix
set aside for 75 mins (at room temperature)
carefully dig out the yolks
carefully brush off the remains of sugar and salt or rinse the yolks (NOTE: if you rinse them: they get really slippy-slimy from the outside, so don’t break them)
serve according to taste (e.g. on toasted buttered bread)
