Here's another way to use natto in a recipe:
Natto bean dip:
pre-made natto beans
garlic
liquid hickory smoke
paprika
onions
parsley
olive oil
salt and pepper to taste
Put ingredients, (your choice of proportions,) all in the blender, or food processor and blend until smooth and creamy. Use it to spread on freshly, baked bread. I made this last night for a family soiree and everyone loved it. I told them it was smokey bean dip. I didn't mention that it was natto. Am I bad?
