Preheat the oven to 200°C / 390°F
Place a cheesecloth or clean kitchen cloth into a colander
Grate zucchinis and place them into the cloth, sprinkle with salt and mix thoroughly
Leave for 10 minutes to allow for the release of excess water from the zucchinis before squeezing them out with your hands (with the zucchini wrapped up in the cloth)
Add the flour, yeast, baking powder and chopped spring onions and mix together.
Add in the melted butter and mix
Fill a cake or muffin tin with the mixture and bake for ~40 mins
Allow to cool before storing. Cut into 8 pieces. If not used within the next 2 days, freeze. They can be stored frozen for up to 3 months.
