I was reading a recipe for Slow Cooker Rosemary Garlic Beef Stew and noticed that one of the ingredients called for a "sleeve" of celery. I've heard of a stalk of celery, but I've never heard of a sleeve. Here is the list of ingredients:  Ingredients    ½ lb. (4 medium) carrots $0.55  ½ sleeve celery $0.65 1 medium onion $0.36  2 lbs. red potatoes $1.00  2 Tbsp olive oil $0.32  4 cloves garlic, minced $0.32  1½ lbs. beef stew meat $9.06 Salt and pepper $0.05  ¼ cup all-purpose flour $0.04  2 cups beef broth $0.30  2 Tbsp Dijon mustard $0.24 1 Tbsp Worcestershire sauce $0.06  1 Tbsp soy sauce $0.10  ½ Tbsp brown sugar $0.02 ½ Tbsp dried rosemary $0.15 ½ tsp thyme $0.05   How much celery do I need to add to the recipe? 
This question is actually answered in a comment to the recipe you linked:     kimberly says:      Sorry for silly question, but the ingredient list says ” ½ sleeve   celery $0.65 “. do you mean 1/2 of a stalk or 1/2 of a bunch of   celery? [...]      Beth M says:      Yes, I meant a half bunch. Sorry about the confusion! :) I used about 4 stalks or so.   They cook down quite a bit.   Also there's a picture of the ingredients used:     So 4-5 stalks appears to be intended amount of celery. A recipe like this though is going to pretty flexible so if that seems like too much or too little it shouldn't be a problem if you go outside that range.
