4. Calculating Food Costs: How Much Do Ingredients Add Up To?
To accurately assess the financial benefits of freeze-drying, you must consider the cost of the food you preserve. This involves evaluating the prices of fresh produce, meats, and other ingredients.
4.1. Cost Analysis of Common Foods
The cost of food varies based on seasonal availability, location, and whether you buy in bulk. Here’s an estimate of the cost of some common foods:
- Beef (Top Sirloin): $12 per pound ($2.91 per 110g dry weight).
- Chicken Breast: $8 per pound ($1.94 per 110g dry weight).
- Pasta: $1.39 per pound ($0.34 per 110g dry weight).
- Tomatoes: $2.29 per pound ($0.55 per 110g dry weight).
- Beans: $1 per pound ($0.24 per 110g dry weight).
4.2. Comparing Fresh vs. Freeze-Dried Food Costs
When calculating costs, it’s important to consider the weight loss that occurs during freeze-drying. Most foods lose about 75% of their weight due to moisture removal. Therefore, you need to account for the dry weight when comparing costs.
- Omnivore Meal Cost: Approximately $3.00 per meal for ingredients.
- Vegetarian Meal Cost: Approximately $1.25 per meal for ingredients.
4.3. Recipe-Specific Considerations
Some recipes may require additional ingredients such as spices, herbs, and sauces. These can add to the overall food cost, but they are typically minor compared to the main ingredients. Rounding up the food costs per meal to $3.00 for omnivores and $1.25 for vegetarians accounts for these extras.
5. Is Freeze-Drying Cost-Effective? A Detailed Analysis
Determining whether freeze-drying is cost-effective depends on several factors, including your consumption level, dietary preferences, and time horizon.
5.1. Break-Even Point Calculation
To calculate the break-even point, compare the cost of freeze-drying your own food with the cost of buying pre-packaged freeze-dried meals.
- Average Cost of Store-Bought Meal: $10 per meal.
- Cost of Freeze-Dried Omnivore Meal: $3.25 per meal (food and operations).
- Cost of Freeze-Dried Vegetarian Meal: $1.50 per meal (food and operations).
The capital costs need to get below $6.75 or $8.50 per meal, respectively, before one starts to save money.
5.2. Consumption Level and Time Horizon
If you anticipate consuming a large number of freeze-dried meals over a long period, investing in a freeze dryer can be cost-effective.
- Omnivore Meals: $2900 / $6.75 = approximately 430 meals.
- Vegetarian Meals: $2900 / $8.75 = approximately 330 meals.
At eight meals per run, that translates to 54 and 41 runs, respectively.
5.3. Long-Term Savings and Benefits
While the initial investment is significant, the long-term savings can be substantial, especially if you consume freeze-dried food regularly. The benefits extend beyond cost savings, including:
- Control Over Ingredients: Ensures high-quality, healthy meals.
- Customization: Allows you to create meals tailored to your preferences.
- Reduced Waste: Preserves food that might otherwise spoil.
- Convenience: Provides a readily available supply of nutritious meals.
6. The Value Proposition: Beyond the Numbers
While the financial aspects of freeze-drying are important, the value proposition extends to non-monetary benefits such as health, convenience, and control over your food supply.
6.1. Health and Nutrition
Freeze-drying preserves more nutrients than other methods, ensuring you get the most out of your food. This is particularly important for individuals with specific dietary needs or health concerns.
6.2. Convenience and Time Savings
Having a freeze dryer allows you to prepare meals in advance and store them for future use. This saves time and effort, especially for busy individuals or families.
6.3. Control Over Your Food Supply
With a freeze dryer, you have complete control over the ingredients and preparation of your meals. This is especially valuable for those with allergies, dietary restrictions, or a desire to eat organic and locally sourced foods.
6.4. Emergency Preparedness and Self-Sufficiency
Freeze-drying provides a reliable way to store food for emergencies, ensuring you have a long-lasting supply of nutritious meals during crises. This promotes self-sufficiency and peace of mind.
7. Optimizing Your Freeze-Drying Process for Cost Efficiency
To maximize the cost-effectiveness of freeze-drying, consider these optimization strategies:
7.1. Bulk Buying
Purchase ingredients in bulk when they are on sale or in season. This reduces your food costs and ensures you have a steady supply for freeze-drying.
7.2. Seasonal Produce
Take advantage of seasonal produce when prices are lower. Freeze-dry fruits and vegetables during their peak season to save money and enjoy the freshest flavors.
7.3. Efficient Batching
Plan your freeze-drying sessions to maximize the use of your machine. Batch similar foods together to optimize energy consumption and reduce the number of runs needed.
7.4. Regular Maintenance
Keep your freeze dryer in good working condition through regular maintenance. This prevents costly repairs and extends the life of your machine.
8. Freeze-Dried Recipe: Posole
Posole is a classic Mexican stew made with hominy in adobo sauce. It is a bit involved to make, but it scales easily, so you don’t have to make it often. It has become one of my trail favorites, especially in cold weather.
8.1. Ingredients Needed
For a roughly 2-quart batch, you’ll need about 6 ounces (170 g) of dried peppers and 4 15 oz (425 g) cans of hominy. Both are available at your local carneceria. For peppers, I recommend guajillos and anchos. Throw in some chipotles (smoked anchos) if you want a smoky flavor.
8.2. Step-by-Step Instructions
- Start by searing the peppers. Cover the bottom of a cast iron skillet with oil, and heat it medium-high until it just begins to smoke. While it’s heating, break or cut off the tops of the peppers, removing the stems and seeds.
- Lay the peppers in the hot oil, searing them until they turn brown (and not too black), about 20 seconds per side. Put them in a mixing bowl of warm water, cover with a dish (to press them under the water), and let them soak for about 20 minutes.
- Pour the peppers and about half the water into a blender and whir it up very fine. Add more water if needed to get a good consistency. Rick Bayless (whose recipe I am adapting here) suggests straining through a cheesecloth, but I prefer a chunkier texture myself.
- Cut up some white onion, drain the hominy, and add both ingredients to the adobo sauce. Sprinkle in some Mexican oregano to taste and simmer for a couple of hours.
- Add pork or chicken if desired.
- Radishes and cabbage are the traditional garnishes, but I usually top with dried flour tortillas strips and some cheese.
- You can save some of the adobo sauce to dry separately. It makes an excellent sauce for other meals – adobo mac and cheese is a fantastic trail meal.
This recipe works for both freeze-drying and heat-assisted dehydration. The hominy doesn’t rehydrate as well if dehydrated and remains a bit chewy. It is still pretty darn good. Give posole a try if you are ready to move beyond burritos.
