How big is a medium onion
I was trying to find out how big a medium onion really is. There such a big size difference between the smallest and largest of onions. I found on Living Cookbook - under the ingredient raw onion that
- Small Onion - 59.25g
- Medium Onion - 122.25g
- Large Onion - 122.25g
- 1 cup - 160g
You will note that the large onion mass (g) is the same as the medium onion which I don’t believe is correct.
Then I found this reference on this website - http://www.onions-usa.org/food_servi...rvice.php#size
Super Colossal 4-1/2" and Up Yellow, Red, and White
Colossal 3-3/4" and Up Yellow, Red, and White
Large/Jumbo 3" and Up Yellow, Red, and White
Medium 2" to 3-1/4" Yellow, Red, and White
Pre-Pack 1-3/4" to 3" Yellow and White
Small 1" to 2-1/4" Yellow, Red, and White
Boiler 1" to 1-7/8" Yellow and White
Creamer Under 1" Yellow and White
Then I found this information on the website - http://www.salon.com/food/francis_la..._large_carrots
Small onion = 4 ounces by weight or about ˝ cup chopped
Medium onion = 8 ounces, or about 1 cup chopped
Large onion = 12 ounces, or about 1˝ cups chopped
Jumbo onion = 16 ounces, or about 2 cups chopped
Now I find myself wanting to find the answer to the onion sizing for small, medium and large onions. The information on the Salon site doesn’t seem right as 8oz = 225g which seems a lot! It also says about that a medium onions is about 1 cup chopped…Living Cookbook says 1 cup = 160g...there is a big difference here. The onions USA site does the sizes in diameter which is not that helpful. I live in New Zealand and we have the Food Standard Australia and New Zealand website (www.foodstandards.gov.au), however everything is measured per 100g, so size does not come into it.
Can anyone out there solve this problem for me?
I use the measures from Cooks Illustrated as I test recipes for them and use their recipes a lot. Please note that the weights given are for whole raw onions with peel etc.
small: 2" 4oz. 1/2 cup chopped=113.398 grams
medium: 2˝" to 3" 8 oz. 1 cup chopped=226.796
large: 4" 1 Lb. 2 cups chopped=453.592
The nutrition information is usually given for a medium onion at 160 grams. That makes sense as you would not include the peel and core when using the onion, hence the lower weight. It is helpful to have the size and cups amounts as some recipes will say e.g., 1 large, others 2 cups chopped, so these figures are useful for conversion purposes to know how many onions to buy or to convert from one size to another (I usually only have large onions on hand).
