How to cook
Knead the freshly ground mince well with the spices and half the carbonated water and leave in a bowl with a lid.
Add the remaining carbonated water in another 2 or 3 lots, stirring well each time. Finally, put the mixture in the refrigerator for 1 night.
The next morning, cut bread into diagonal slices and smear them with plenty of minced meat. Put them on a grill or a grill pan with the minced meat side down and bake until ready.
