Ingredients:
The peas should be the dried marrowfat ones. The best ones we have found in the UK are Bachelors Bigga Marrowfat Peas. Place the peas in a large dish with plenty of room as they will expand when soaked. The peas need to be covered with two to three times their volume of boiling water. Add the steeping tablet that came with the peas or a couple of teaspoons of bicarbonate of soda if there are no tablets. This is important as the peas will not break down unless the bicarb is added. Cover and leave overnight.
The next day drain the peas and put them in a pan with enough fresh water to just cover them. Bring to the boil and simmer for about 20 minutes. The peas should break up nicely. Add a little water to the mixture to loosen the mushy peas to the consistency you like. Season only at the end, as if you do so before that the peas will be tough. Mushy peas freeze well.
