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 .
1 teaspoon yeast powder
3 and a half cups flour
1 and a half cups hot water
1 teaspoon Salt
3 teaspoons baking powder
Put the hot water in a large bowl
sprinkle the yeast in it and stir
add 3 cups of flour, salt and baking powder
mix until you get a good dough ball , add more flour until its not sticky
place a piece or wax paper in the slow cooker and place the dough ball in the center
put the slow cooker on low for 1 hour, the dough should rise and double in size.
set the slow cooker to hot and bake for 2 hours Remove and let the bread cool on a cooling rack before eating
can substitute the 1.5 cups of water, with half a cup water, half a cup milk and one egg. Or melted butter , and milk and and egg . so long as its around 1.5 cups of liquid. Experiment , its fun
