What Happens When You Use Water?
When you combine instant pudding mix with water, the outcome is largely unsuccessful, and for reasons that are rooted in the basic chemistry of the product. Unlike milk, water lacks the essential proteins and fats necessary to activate the thickening agents within the instant pudding powder. Instant pudding mixes, such as those from Jell-O, often contain phosphates, which interact specifically with dairy proteins to create a firm, gel-like structure. Without these proteins, the mix cannot properly set, leaving you with a disappointingly thin and watery mixture, not a creamy pudding. A user on Reddit who tried this reported that they needed to add a second pudding packet just to get a minimal set, and even then, the flavor was described as flat and missing something.
The Texture: A Soupy Mess
One of the most noticeable failures of using water is the texture. Instead of a thick, smooth, and creamy pudding, you will get a thin, soupy liquid. The mixture might thicken slightly but will never achieve the desired firm or custard-like consistency that makes pudding so enjoyable. The extra effort of adding more mix or letting it set longer will likely not be enough to fix this fundamental issue, leading to wasted ingredients and a disappointing dessert.
The Flavor: Flat and Unappetizing
Milk provides a rich, creamy flavor base that water simply cannot replicate. By omitting milk, you are left with a bland, one-dimensional taste that is overwhelmingly sweet, but without the satisfying mouthfeel. The instant pudding mix contains a high concentration of sugar and flavorings meant to be mellowed and balanced by the fat and proteins in milk. Without this balance, the artificial flavors can become overwhelming or simply unappetizing. Experienced home cooks strongly advise against this substitution for this reason alone, recommending that it is always best to find another liquid or postpone making the pudding.
Better Alternatives to Milk for Instant Pudding
If you find yourself without milk or need a dairy-free option, there are several superior alternatives to plain water that can save your instant pudding. While some require minor adjustments, they will produce a much more satisfying result than a watery mixture.
Non-Dairy Milks
Plant-based milks are a popular choice for dairy-free diets, but they require a specific approach for instant pudding. Many instant pudding brands explicitly warn that their mix will not set with soy milk or other non-dairy milks. This is due to the lack of the specific casein proteins found in cow's milk. However, with a few modifications, it is possible to achieve a good result.
- Almond Milk: Use a bit less almond milk than the recipe calls for, as it's thinner than cow's milk. You can also try adding a thickening agent like cornstarch (see how-to in the table below).
- Soy Milk: Soy milk has a richer texture than almond milk, making it a decent option, though it may still require an additional thickener.
- Coconut Milk: Full-fat canned coconut milk is an excellent alternative due to its high fat content, which mimics the richness of dairy milk. It does, however, add a distinct coconut flavor, so choose your pudding flavor accordingly.
Other Options
- Powdered Milk: This is a perfect solution because it is, in essence, milk with the water removed. Just reconstitute the powdered milk with water according to its package instructions before adding it to the instant pudding mix. This ensures you have all the necessary proteins and fats for proper setting and flavor.
- Condensed or Evaporated Milk: For a richer, more decadent pudding, you can use canned evaporated or condensed milk. Be aware that these are much thicker and sweeter than regular milk, so you may need to dilute them with some water and adjust for sweetness. The high fat content will ensure a luxurious, creamy texture.
How to Salvage Watery Instant Pudding
If you have already mixed your pudding with water and are left with a runny liquid, you're not entirely out of luck. There are several ways to rescue the mixture, though the flavor may still be compromised compared to a milk-based pudding.
Methods for Thickening
- Add More Mix: The simplest solution is to double the amount of dry pudding mix for the same amount of water. This is essentially what the Reddit user did to get it to set.
- Use a Cornstarch Slurry: For cook-and-serve puddings, a cornstarch slurry can activate the thickening. Whisk 2 tablespoons of cornstarch with a quarter cup of cold water until smooth. Add this to the pudding mixture in a saucepan and bring to a boil over medium heat while whisking constantly. Continue to boil for 2-3 minutes until thickened. The pudding will continue to set as it cools.
- Incorporate a Dairy-Free Whipping Cream: Blending in a dairy-free heavy whipping cream alternative (like those from Silk or Country Crock) can help thicken the mixture and add richness. This will also make the final product more of a mousse-like consistency.
Instant Pudding Comparison: Milk vs. Water vs. Alternative
| Characteristic | With Cow's Milk (Recommended) | With Water (Not Recommended) | With Non-Dairy Milk (Modified) |
|---|---|---|---|
| Texture | Smooth, thick, and creamy | Thin, watery, and often soupy | Thicker than with water, may need cornstarch to set properly |
| Flavor | Rich and balanced, as intended | Flat, bland, and overly sweet | Varies by milk, often slightly less rich; may have nutty flavor |
| Setting Time | Sets quickly, typically within 5-10 minutes | May not set, or will set very poorly, even with refrigeration | Slower than with dairy milk, often 30 minutes or longer |
| Cost | Regular milk cost | Low cost | Varies by type of milk, can be more expensive than cow's milk |
Conclusion
While the urge to use water when milk is unavailable is understandable, the chemical and structural differences between the two liquids make it a poor substitute for instant pudding. The lack of proteins and fats in water results in a watery, flavorless, and unsatisfying dessert. For the best result, stick to the instructions on the box and use dairy milk. If dairy is not an option, excellent alternatives like powdered milk or modified non-dairy milks will produce a much more pleasant outcome.
