Clean: Food safety starts here!
Wash hands for 20 seconds
- Wet hands under hot running water. Add lots of soap.
- Rub and wash back of hands, wrists, between fingers and under fingernails for 20 seconds.
- Rinse well under running water.
- Dry with paper towels.
- Use paper to turn off the water faucet.
Clean and sanitize sink and counter tops
- Wash counter tops and prep sinks with hot soapy water.
- Fill squirt bottle with 1 quart water. Add 1 teaspoon of chlorine bleach or use commercially prepared cleaner per directions on label.
- Spray counter tops and sink with bleach solution. Let air dry.
- Wash hands.
Clean as you go
- Wash dishes, utensils, cutting boards, etc. in hot soapy water.
- Let air dry.
- Put away items where you found them.
Select firm, tender, well-colored rhubarb stalks with good flavor and few fibers.
- Rinse rhubarb well under running cold water using a produce scrub brush.
- Cut off the ends using a knife and cutting board. Remove any bruised or damaged areas.
- Cut rhubarb into 1 inch pieces.
- Heat rhubarb in boiling water for 1 minute and cool promptly in cold ice water for 1 minute to help it retain color and flavor.
- Drain well removing as much water as possible to prevent ice crystal formation during freezing.
- Package. For a dry pack (without sugar), tightly pack the preheated rhubarb into containers, leaving ½ inch headspace. You could also freeze the slices in a single layer on a baking sheet just until hardened, then pack dry into your containers. Tray freezing is the best way to have loose slices easily removed from the package.
- Label the lid
- Name of product
- Form of food (example: dry pack, no sugar)
- Amount (example: 2 cups)
- Seal the lid on the container, releasing all the air. Make sure all edges are sealed tightly before freezing.
- Freeze. Place the packaged rhubarb in the freezer in an upright position. An upright freezer, chest freezer, or refrigerator-freezer combination can be used as long as it can reach a temperature of 0° F or below. Keep a thermometer inside the freezer in order to keep track of the temperatures at all times.
