The best results I have had are with red clover, China Rose radish, alfalfa, mung beans, lentils, sunflower and chickpeas. Broccoli seeds are lovely but they do take an age and you will need the jam jar type of container and lots of water to rinse them over the week or so they take to sprout. China Rose radish are my favourite and are one of the quickest to sprout.
The tray sprouters pictured are by Being Fayre and have three sprouting levels but you can combine as many kits as you like. I have been know to have 9 levels on the go at once. You can use any organic seeds but the most cost effective way is to buy them in bulk and I get mine from Aconbury Sprouts. 500g of China Rose radish costs less than £6 and you only need one heaped teaspoon per layer. Amazing value for money.
So how to sprout.....
Soak one heaped teaspoon of seeds per layer for around 8 hours in clean filtered water. I soak mine in the green drip tray. After the soaking time pour into the sprouting tray and rinse with filtered water. All you have to do is rinse the trays twice a day until the seeds have sprouted. Usually between 3 and 7 days. For the last day place in sunlight and once fully sprouted let them drain for an extra 12 hours. If you do this last step of allowing them to fully drain they will keep in the fridge for up to a week.
It is really important to clean the trays thoroughly.
Try and eat a cup of the sprouts every day - use instead of lettuce in the winter for a lovely, amazingly fresh side dish.
