Does Pressure cook work for hard to soften soybeans?

Question

I do not have a pressure cook in my house. But the soybean I bought remains really hard after soaking for 24 hours and boiled for 1 hour. I saw someone saying that some old beans will never soften no matter how long I cook. Is this really true?

One of the poster mentioned 10 min cooking in a pressure cook should soften the beans. This appeals to common sense. But I am still concerned about those people saying "will never soften no matter what".

So, I am asking if any one has tried boiling which did not work but succeeded to soften the beans with pressure cook? I have no need for a pressure cook. And I don't want to buy a pressure cook if it too can not soften stubborn hard soybeans.

Answer 1

Tried it. Failed utterly. If the beans won't soften with overnight soaking and an hour of cooking, you should forget about them.

Answer 2

Soya beans take from 4-6 hours of gentle boiling/ simmering to cook. They're a pain in the ass! They would take maybe 40 minutes in a pressure cooker even. I hate them, but this is the normal cooking time for them.
