Dec. 2017 Trail Bytes: How much water is needed to rehydrate a dried meal?
December 07, 2017
Hello,

What to do with the holiday leftovers?

After Thanksgiving, I made chicken cacciatore out of leftover chicken and rice; then dehydrated it. In the process, I documented an easy way to portion a meal and determine how much water is needed to rehydrate it.

Chicken Cacciatore

Serves 2

  • 4 cups cooked rice
  • 12 ounces chopped cooked chicken
  • 1 15-ounce can diced tomatoes including liquid
  • 8 ounces sliced mushrooms
  • 1 medium onion, diced
  • 2 cloves garlic, diced
  • Pinch each of herbs such as thyme and basil to taste
  • Salt and pepper to taste, start with ½ tsp salt
  • 1 tsp cooking oil

Cook onions and garlic lightly with one teaspoon cooking oil. Use some of the liquid from the diced tomatoes instead of using more oil.

Add diced tomatoes with liquid, plus herbs, salt, and pepper. Bring to a low simmer for five minutes, then stir in cooked rice and cooked chicken.

Once the ingredients are warmed through after a few minutes, adjust salt and pepper, and let cool.

Spread two cups of chicken cacciatore on each dehydrator tray covered with a nonstick sheet. Dehydrate at 135° F. It should be dry in approximately nine to ten hours.

The Easy Way to Portion a Meal and Determine How Much Water is Needed for Rehydration

I started out with two cups of cooked chicken cacciatore on each Excalibur Dehydrator tray for three reasons:

  1. It’s a good quantity of solid food to dry efficiently.
  2. It’s just the right amount of food for me to eat in one meal.
  3. It’s easy to slide the dried food from the tray directly into a Ziploc bag, saving the trouble of measuring again later.

Using a digital food scale, I weighed the two cups of food before drying and then after drying.

Beginning weight of two cups of chicken cacciatore was 14.2 ounces (402 grams).

Dried weight was 3.2 ounces (90 grams).

402 grams – 90 grams = 312 grams of water weight removed during dehydration.

What comes out, must go back in, so at least 312 grams of water would be needed to rehydrate the meal. That amounted to a little less than one and a half cups of water. (I weighed the water). I rounded up to an even cup and half (12 fluid ounces or 3.5 deciliters), since I rehydrated the meal in a thermos food jar over several hours. If I had rehydrated the meal in a pot for quicker consumption, I would have used a little less water.

This strategy of weighing and creating equal portions per tray can be a time saver when dehydrating a large quantity of the same meal. There is no need to weigh the food on each tray if you put two cups worth on each tray. Just use the weight data from the first tray as a guide, and you will know how much water to use for rehydration.

How was it?

Tasty. As expected, the chicken was a little chewy, but acceptable. It’s best to tear it into small pieces before you dry it.

Are you dehydrating leftovers for trail meals? Let me know what works well for you, or if you have any questions.

Santa has a couple of informative and entertaining books he'd like to leave under your tree. Writing the trail journal was a great experience, as was the hiking. I think you will enjoy reading it.

Dominique and I wish you good hiking and much happiness during the holidays. See you in 2018.

Freundliche Grüsse,

Chef Glenn & Dominique
