Most families don’t eat 10 gallons of chili at one time, so if you’re planning to enter Saturday’s cook-off, then some editing of your favorite family recipe is in order.
Note that scaling a recipe increases subtle errors built into them. For instance, the salt needed for a small recipe may not be exactly one-half or one-quarter teaspoon, so the amount is rounded to the nearest measurable amount. The difference is negligible at such a small level, but at larger volumes, that extra amount really shows.
Try adding seasoning a little at a time, tasting using a clean spoon, to build to the given amount.
When scaling a recipe the simplest method (even for Lifestyle Writers) is to use a conversion factor formula.
For example, the recipe below yields 50 8oz. servings or 400 oz. or 3 1/8 gallons of chili. To get to the 10 gallons that the Manchester Fire Department recommends cook-off contestants bring, divide the desired yield (1280 oz.) by the given yield (400 oz.) for a conversion factor of 3.2. Next multiply each ingredient by 3.2. The 10 lbs. of hamburger meat times 3.2 equals 32 lbs. of beef. Likewise, 2 lbs. of onion times the CF gives a required 6.4 lbs. of onions. Using weight instead of volume adds precision.
10 lbs. ground beef
2 lbs. onion, chopped
2 lbs. green pepper, chopped
10 lbs. canned tomato
2 lbs. tomato puree
2 oz. chili powder
1 oz. salt
1 teaspoon cayenne pepper
2 10# cans beans (pinto, red or kidney) drained
Heat large skillet. Working in batches, brown meat, breaking into small pieces. Transfer in to several stockpots.
Repeat procedure with onions and green peppers, cooking until soft.
Add remaining ingredients, dividing among stockpots. Bring to a boil and simmer on medium-low, stirring occasionally, for an hour.
Add beans and simmer for an additional 15-20 minutes.
