Red Kidney Bean Ama-Natto 甘納豆

I made Ama-natto of butter beans and chic peas last year. This time I'll show you the another recipe. 

This Ama-natto（甘納豆）made by Red Kidney Beans.
There're many variety of Ama-natto as I made before. 
Soy beans, butter beans, chic peas etc, any beans and peas you can use for Ama-natto. I prefer using quite big beans. Dry or tined,,, doesn't mutter.
Sometimes you can use the vegetables like sweet potatoes and pumpkins. 
Oh, chestnuts are so good.

This recipe;
250g Red Kidney Beans
250g sugar (can be used less sugar)
1/2 tsp salt
and
some granulated sugar (option)

Soak the dry beans overnight.

Boil the beans in low heat very gently, maybe for over 1 hour, until the beans are softened. I want to keep the shape the beans so don't stir too much.
Through out some water (See picture left).
Put the same or less quantity of sugar into the this pan.
Leave the beans in the sugary water overnight or one day.

After another soaking,
Drain the beans. Maybe leaving in the colander or sieve for hours would be good idea.
Spread the beans evenly on the tray and place the tray in the oven at 70℃ and leave it until the beans are a little dry. But not too dry. The beans will be hard to eat. You don'y need to use the oven, just dry them at the room temperature. 

Coat the beans with the granulated sugar. 
If you don't like it, you don't need to add any sugar. It's option. But the letter Ama（甘） means sweet so a lot sugar is normal.

The Ama-natto can be frozen for a quite long time.
