David B. Thomas inquired recently about how hard it was to make your own Sodastream-style machine at home. For those unaware, Sodastream machines are home soda-making machines. They involve a countertop appliance, CO2 canisters, and specialized bottles to carbonate water and then add flavoring.

The answer to Dave’s question is, not terribly hard – and much more cost effective in the long run. A two-liter bottle of regular grocery store soda will cost around US1.50 – US2. A bottle of Sodastream soda at equivalent volume (two liters) will cost about US0.50. A bottle of homemade soda with the equipment below? Probably about US0.03.

One of my annoyances at the Sodastream I owned was that I had to change out the canister every month or so; it made about 30 liters of carbonated water, which was okay. In typical hacker fashion, I asked, what if I could do this myself? What if there were better gear? It turns out that of course, there is significantly better gear to be had – from the beer world. Beer kegs tap CO2 and/or nitrogen all the time to add that last little punch to a brew. The equipment is surprisingly simple.

What you’ll need to buy (some links through Amazon Associates):

• A CO2 canister. Most welding shops carry these. I paid $100 for a 10 pound canister. Unlike a Sodastream, this lets me make about two liters of soda a day for close to a year.
• A length of hose with clamps to connect the tank to…
• A dual pressure gauge regulator. This tells you how much pressure is in the tank, and lets you set the pressure for your soda water. I usually set mine to 40 PSI.
• A ball lock and hose. This goes from the regulator to your bottle of soda and connects to…
• The Carbonator. This plugs into the ball lock and is what connects your soda bottle to the whole business.
• A used soda bottle, clean and free of cracks.

This is the best part: you get to recycle. Sodastream bottles aren’t dishwasher safe, so over time they can get nasty, and of course, buying a new one costs a fair bit for what’s essentially just a plastic bottle. A used soda bottle obviously can hold soda (at much higher pressures), so recycle!

Assemble these pieces in the order above.

When put together in order, you get this:

The trick with making soda at home is to have the water be ice, ice cold. I usually fill the soda bottle with about two cups of fresh water and then place horizontally in the freezer. This turns into a giant ice cube.

Once thoroughly frozen, fill to the point where the side of the soda bottle begins to curve, near the top of the bottle where the label ends.

Then attach to the carbonator, turn on your gas, and shake vigorously while the CO2 dissolves in the water. After a minute of vigorous shaking, turn off the gas, remove the bottle, and enjoy!

Enjoy your DIY Sodastream-style soda maker!

Every year at the office potluck, I try to find new and different ways to make stuffing that requires the largest, longest possible warning sign while still being delicious. Why? It’s the fun and challenge of kitchen chemistry. Fortunately, lots of people bring different kinds of stuffing, so it’s not as though mine were the only one available. I also print out the warning sign next to the serving dish so that no one mistakes it for ordinary stuffing.

Your Responsibility

If you make this dish, you too have a responsibility to disclose its contents and provide warnings to people with allergies. Allergic reactions to food can have serious, even life-threatening consequences, so please use this recipe responsibly.

Feel free to download and print out the warning sign I use.

Ingredients

Visible Solids

• 2 packages Pepperidge Farm seasoned bread stuffing, non-organic, GMO
• 1 cup of mushrooms, finely chopped
• 1 cup of onions, finely chopped
• 1 cup of carrots, finely chopped
• 2 tablespoons garlic, minced
• 2 tablespoons sesame seeds
• 1/4 cup unsalted mixed tree nuts – pistachio, almond, walnut, and cashew, finely chopped
• 2 tablespoons unsalted peanuts, finely chopped
• 2 tablespoons parmesan cheese
• 1 cup rendered bacon, finely chopped

Liquid Base

• 1 teaspoon of Aji-no-moto hondashi fish soup stock powder (with MSG)
• 1 teaspoon of Chinese oyster sauce
• 1 teaspoon of regular ketchup, non-organic, GMO
• 4 cups of water, unfiltered
• 1 teaspoon of honey, with pollen
• 1 egg

Frying Base

• 1 stick of unsalted butter, non-organic
• 1 teaspoon sesame oil
• 1 teaspoon soybean oil
• 1 tablespoon bacon grease

Directions

• Render bacon in pan or skillet.
• Remove and drain bacon. Allow to cool. Set aside grease.
• In a very large skillet or wok, melt butter and mix with soybean oil, sesame oil, and bacon grease.
• Add chopped nuts, garlic, and sesame seeds. Fry until nut meats begin to turn translucent. Do not permit contents to burn.
• Add all vegetables to pan and cook until onions begin to turn translucent.
• Put contents of skillet into large metal bowl.
• Add all liquid base components to bowl.
• Stir vigorously until liquids are blended thoroughly.
• Add all remaining solids and stir vigorously until thoroughly mixed.
• Cover bowl with aluminum foil and place in 375F oven for 90 minutes, checking and stirring contents every 30 minutes.
• Print out the included warning sign to alert people with food allergies and religious dietary restrictions.
• Serve.

Some Notes

If you make substitutions, particularly on the liquids, watch your sodium counts. One substitution, like a chicken broth, could make the dish inedible because it would put the salt content over the top.

A bit of backstory about this particular recipe: I learned it thanks to the power of marketing years ago. I was speaking at the Educational Travel Conference, and at the conference, the trade show floor could only be described as culinary magnificence. Many of the exhibitors were educational departments of embassies, and few things demonstrate a country’s cultural riches like native food.

At the event, I grabbed what looked like a shot glass filled with… something… and I took a bite of the contents. It was magnificent – citrus, sour, salt, fresh herbs, and fish. I had no idea what it was so I asked the sous chef of the Chilean embassy who told me in halting English that it was called ceviche, a seafood dish popular in many South American countries. He said what made Chilean ceviche different was that only the Chileans used grapefruit juice, while other countries stuck to lemon or lime, and only Chilean ceviche used cilantro. I’ve no idea whether there’s any culinary truth to that particular origin story, but I don’t care, either: it’s delicious.

The recipe I found that day called for Chilean sea bass, a nice name for the Patagonian Toothfish (which is a marketing coup in its own right), but I find that tilapia makes for a better taste and texture. It’s entirely up to you which kind of white fish you use as long as it’s relatively mild in flavor. If you’re concerned about freshness and food safety, I recommend buying deep-frozen tilapia filets; deep-frozen fish is generally very safe as long as it’s thawed properly.

Ceviche Ingredients

Solid Ingredients:

• 2 pounds tilapia or other white fish
• 1 onion
• 1 cucumber
• 1 celery heart
• 1 yellow bell pepper
• 1/2 cup cilantro
• 2 large tomatoes or 1 can of diced tomatoes

Marinade Ingredients:

• 2 cups white grapefruit juice
• 1/4 cup lime juice
• 1/4 cup lemon juice
• 1 tablespoon salt
• 1 teaspoon black pepper
• 1/2 teaspoon honey or 1/8 tsp pure stevia powder
• 1 jalapeño or 1/2 teaspoon jalapeño sauce
• 1 clove of garlic or 1 teaspoon garlic powder

Ceviche Directions

1. Dice the solid ingredients. Aim for all chopped ingredients to be about 1 centimeter (1/2 inch) in size.
2. Place solid ingredients in a large, non-reactive container (like a glass pitcher or bowl).
3. Put all the marinade ingredients in a blender and blend until thoroughly mixed.
4. Pour the marinade over the solid ingredients, ensuring everything is submerged.
5. Add additional grapefruit juice if necessary.
6. Refrigerate for 4-6 hours. The acid in the juice will “cook” the fish.
7. With a slotted spoon, serve in glasses. Some people like tortilla chips as an accompaniment.

Try the Ceviche Recipe!

Chilean-style ceviche is a wonderful dish any time of year, but it’s especially refreshing during the hot summer months when you want something that isn’t going to make you feel any warmer. It’s easy to prepare, tasty, and healthy, too; the dish is gluten-free as prepared.
