Mum's potato with garlic and vegeta

• Peal potato, halve into half along the long edge so that you can lay it flat.
• Cut multiple seams into the potato but don't cut it through.
• Cut garlic into thin slices and put it between the slices of the potato.
• You can salt the potato a bit on the top.
• Smear butter all over the baking tray.
• Half of the potato should swim in the water (put more water in there if it boils off too much).
• One tablespoon of Vegeta (or vegetable stock) per 200 ml.
