Everything You Need to Know About Cooking With Hard Water

You may be a better cook than you think… Hard water may silently sabotage your home-cooked meals. Have you ever wondered why it seems your pasta has been boiling forever and is still a little too hard? Or why the bitter taste of your favorite morning coffee flavor is not tasting quite right? Hard water can affect several aspects of your daily life, including home-cooked meals. But what does this mean and how can you fix it? Let’s dive in and find out exactly how the type of water you use can affect your cooking and the solutions to these issues!

Yes! You can cook and bake with hard water, however, there may need to be adjustments made to achieve the results expected. The mineral content levels in hard water can affect several aspects of cooking and baking, including the need to adjust recipes.

Hard water’s increased mineral content can affect the cooking time, the food’s texture and taste, and your food’s safety.

Hard water can cause an unpleasant taste when preparing some food and beverages. For example, hard water can create a metallic taste in coffee and teas. The minerals in hard water can counteract the flavor of coffee. Hard water can have a similar effect on soups and sauces, changing their flavor profile to create somewhat of an unpleasant taste, rather than what was intended when following the recipe.

Water hardness can also affect solid foods. When boiling vegetables or pasta in hard water, the final food product may taste more ‘earthy’ or ‘mineral-like’ than if it was cooked with softer water. This is because foods such as pasta and rice, absorb water while they cook, in turn, they absorb the minerals in hard water.

Hard water can also change the texture of certain foods. In the case of vegetables and pasta, hard water can cause longer cook times and tougher textures than usual. It can also cause some solid foods to be denser.  

The canning and pickling of foods can be affected by hard water. The minerals in hard water can cause the growth of bacteria and reduce the effectiveness of sanitizing and preservative practices.

Baking can become quite the science, between making sure the temperatures are just right and ingredients are perfectly measured. Hard water can interfere with the gluten formation of baked goods, causing them to become denser or have a less-than-desired texture. It can also interact negatively with yeast and baking powder, which can prevent the rise of dough.

In some instances, hard water can interfere with your cooking to the point of adjusting the recipe to get it just right.

Hard water has a higher boiling point than soft water. While the difference in boiling point between hard and soft water may only be a few degrees, it is important to note, as it can affect your meal preparation.

Due to the effects the mineral content in hard water has on yeast and baking powder, your recipe may benefit from adjusting the amount of these ingredients used to compensate for the minerals in the water. Lemon juice and vinegar are known to help counteract the effects of hard water on recipes.

You may want to start a recipe a bit sooner than the recipe calls for to account for the additional time that is needed for hard water to reach its higher boiling point, lengthening the cooking process.

For example, when cooking pasta and grains, the food will likely require a longer cooking time than the recipe calls for to achieve the desired texture of your recipe.

While cooking and baking with hard water may cause a few challenges, there are a few tips that can help make the experience easier and reduce the headaches hard water may cause in your kitchen.

Build-up caused by hard water can pose a significant challenge to the way cooking equipment works. The scale buildup from hard water can reduce the efficiency of your equipment which can lead to an increase in energy consumption. This build-up can affect any appliance that uses hard water, from blenders to your coffee maker.

There are a few ways to rid yourself of the kitchen headaches caused by hard water once and for all.

1. Water Softeners are designed to remove the minerals that make water hard, calcium and magnesium, from your water. These systems use a process called ion exchange to replace these minerals with sodium or potassium ions, giving you soft water.

2. Reverse Osmosis Systems are effective in reducing hardness as well as other contaminants in your water. These systems use a semipermeable membrane to remove impurities, including the minerals that make water hard, calcium and magnesium.

3. Whole House Filtration Systems treat your entire home’s water supply. These systems can help reduce hardness, as well as other impurities, ensuring that all the water you use in your home is of high quality.

According to a U.S. Geological Survey, general water hardness is caused by compounds of calcium and magnesium, and by a variety of other metals. Hard water is measured on a scale, from not hard, to very hard. General guidelines for the classification of water are:

·      Soft Water: 0 to 60 mg/L (milligrams per liter

·      Moderately Hard: 61 to 120 mg/L

·      Hard: 121 to 180 mg/

·      Very Hard: 180 mg/L

Some signs and symptoms of hard water are soap scum, dry hair, and skin, and clogged pipes and water fixtures. To find out how hard your water is, get a free water test!
