Wash and brush the potatoes well with a natural fibre brush. Make a few incisions and then beat them with a meat mallet. Rub them with oil and the other seasoning ingredients.
Microwave cooking
Divide the potatoes into the jars, add a sprig of rosemary and a clove of unpeeled garlic to each one. Clean the edges of the jars well, close and hook the 4 clamps. Insert in the microwave (or in the Ultracombi in microwave mode) for 8 minutes at 800 W. Then let it rest for 20 minutes before consuming.
Storage
Store in the fridge for no more than 5 days.
