Check my math...

I'm making a huge pot of split pea soup today for a crowd. According to the bag of dried peas, each bag contains 13 servings @ 90 cals each. I am making 4 bags. So 52 servings total in the pot. I'm using 32 cups of water (lid on so I should lose much in steam).

52 servings / 32 cups = 1.62 servings of peas in each cup. 1.62 * 90= 145.8 cals per cup served.

If I up the water another 8 cups if it's too thick while cooking, then it's 117 cals per serving ((52/40)*90).

Does this sound right? Is there a better way to figure this out?

I'll calculate the ham separately and add a weighed amount to my bowl when we eat.

Are you adding other things to the soup? Veggies? Chicken broth? Just water and peas?

I found the easiest way for me when I make pea soup is to throw it all in the recipe builder here. Especially if I know how many portions it makes.

No veggies but I will add broth cubes. Was going to figure out the math for those with the same formula if it was right. Yeah- I've tried the recipe calculator too but I noticed on more than one occasion it may say the servicing is 200 cals but when I apply it to my log it shows a different lower cal amount. Figured I must be doing something wrong with it so I don't use it. I'll plug it in there and see what it says.

You are forgetting the weight/volume of the peas themselves. Get the package of peas out and note the total weight of the peas (e.g. 16oz). Then multiply the weight of the peas (e.g. 4x16=64oz) and add that to the weight of the water (32x8=256oz). So the total weight of the peas and water is 320 in this example. 320/52 servings = 6.15oz per serving, or you could choose 8oz servings 320/8 = 40 servings.

Someone else should check my math, though.

Edited to add:

Bottom line though, if you are cooking only peas with water and adding nothing else, then 13 servings per bag multiplied by the calories per serving yields the total calories in the batch. 13x90x4=4,680 calories total. Then just divide that by the number of servings, bearing in mind that the total ounces of your serving (either 6.15oz or 8oz in the above example).

So, 4680/52 = 90 calories for a 6.15oz serving (52 servings)

Or, 4680/40 = 117 calories for an 8oz serving (40 servings)

Does that make sense?

Ok! I see what you are saying. It does make sense.

So total oz of peas is 64 + 256 oz of water =320
320/ 52 = 6.15 oz. serving
6.15 oz.= 90 cals.
(90/6.15)*8 = 117 per 8 oz serving

I never would have thought to do the math that way! Thank you!

Its not you. The recipe builder does that sometimes. You just go back in hit edit recipe then save again and it should fix itself. I have had it happen on multiple recipes.

And this is why it's so much easier to use weight...
