This fruit and berry farm produce chart from 1948 is for Indiana. The information of when to purchase at the farm or farmer’s market can be ballpark adjusted to your area. When I lived in central Midwest, surprisingly a farm I visited had a bushel of healthy small tomatoes to “can” for under $20! Aside: Don’t talk farmers down on price. $20/bushel can’t be the prices today, but, please, find a place near you, if you’re inclined. The tomatoes I got were without pesticides or chemical fertilizers, yet legally couldn’t be labeled organic. What a price surprise, and what resources. This is an important resource link for finding pick-your-own farms, which is a wonderful start!
Another interesting fact from the above chart, is in small print at the bottom they give the quantity in “numbered” canned foods — if you have a vintage recipe and wish to figure what is a #2 can, for instance, as that was food manufacturer’s labeling back then — confusing for food shoppers, but logical to their manufacturing process —
Number #2 can = a little more than a pint
Number #3 can = 1 quart
