If you didnt have yeast when lockdown started – you can make it from the natural yeasts that are in bread flour, with a little hot water and some time.

Take a large jar and put one table sppon of hot water and one of flour in the jar, stir until its well mixed,

Leave the jar covered with a clean cloth for 5 days in a warm place, adding a teaspoon of flour and and equal amount of warm water every day until the mixture starts to bubble . It can then be stored in the fridge and to keep it going add a table spoon of flour and water once a week.

If its starts to smell bad or turns any strange colours – toss it out and start again.

To use the yeast, add a large tablespoon of the mixture to the bread flour when making bread .
