A 15.5 oz can of beans will not contain 15.5 oz of white beans. What is the drained weight? You will find that it is less - probably about 12 oz which is about 6 oz of dried beans before re-hydrating (soaking and cooking).
Usually, dry beans which require re-hydration (soaking in water and cooking before use) will double their weight. Thus 100gm dry weight of raw dried beans will give, after cooking about 200gm of drained cooked beans. IIRC a 15.5 oz can is about equivalent to a 454 gm can, but drained will be much less and the drained weight should be noted on the can. The drained weight might be anything between 320gm-375gms once the water has been drained off!
The dried beans should be soaked overnight in lots of cold water or cover with lots of boiling water and leave for a few hours. Drain the beans, place in a pan with fresh cold water, a bay leaf, a peeled, quartered onion, a couple of cloves and a couple of black peppercorns and bring to the boil. Cover, reduce heat and simmer until cooked. cooking times may vary depending upon the type of white bean and the age of the bean - older beans take longer to cook than newer beans. Drain and use in the recipe. Do not salt beans until they are cooked.
Hope this helps,
