[header] How to boil peanuts [title] Select the right peanuts for boiling. [step] Jumbo peanuts or valencia peanuts are preferred by many, but most standard peanuts work well, so long as they are still green. Do not attempt this recipe with roasted peanuts, as they will not become soft, no matter how long you cook them. 
In the south, farmer's markets and roadside vendors sell green peanuts from early summer through late fall or first frost. Dry/raw peanuts can be enjoyed year round but need to be soaked in water 24 hours before boiling.
