Here’s the sick thing… I did the math and my homemade jam costs about as much per ounce as Bonne Maman’s high-end grocery store jam: $0.22 per ounce.
I made 30.5 pints of jam, using 34 jars (some were half-pint jars for gifts), inputting 28 lbs of strawberries, 7 packets of Certo pectin and 21.462 pounds of sugar.
Here’s the breakdown:
- Jar and ring – reusable and depreciating resource.
- Canning equipment – depreciating resource.
- Canning jar lid. $1.99 for 12 = $0.17 per lid, or $5.78 for lids.
- Sugar. $2.59 at the COOP for a 4 pound bag = $0.65 per pound or $14.07 for sugar.
- Strawberries at $2.50 per pound and 28 lbs of berries into the recipe = $70 for strawberries.
- Certo is $4.59 for 2 pouches = $2.30/pouch so $16.10 on pectin.
Grand total = $105.95 for 30.5 pints of jam. That’s $0.22 per ounce.
Bonne Mamans jam was on sale at the COOP for $2.99 for a 13 ounce jar or $0.23 per ounce.
I hope some of you are jumping up and down right now and pointing out the serious flaws in my calculation… I don’t take into Labor costs, which was about 13.5 woman-hours. I don’t take into account the cost of my “facility” to produce jam. I don’t take into account transportation, and I’ve discounted my equipment. But hey! My jam is a heck of a lot tastier than anything you’d ever buy in a store. Plus I have a great memory of spending a hot, muggy day in the kitchen with my sister. That’s worth a lot more than $0.23 per ounce.
