Reviving a Classic: How to Make Old Fashioned Buttermilk
Buttermilk, a timeless beverage that has graced the tables of many cultures, is often overshadowed by its modern counterparts. However, this tangy, refreshing drink deserves a place in our kitchens once again. Here, we'll guide you through the process of making old fashioned buttermilk, complete with its rich history and cultural significance.
Understanding Buttermilk: A Brief History
Buttermilk, a byproduct of butter production, has been a staple in many societies for centuries. Traditionally, it was the liquid left behind after churning cream into butter. The term 'buttermilk' is believed to have originated from the Dutch word 'boetermelk', which translates to 'sour milk'. Over time, the process of making buttermilk evolved, leading to the creation of cultured buttermilk, which we'll focus on in this article.
Ingredients and Equipment
Making old fashioned buttermilk requires minimal ingredients and equipment. Here's what you'll need:

- 1 quart (1 liter) of whole milk
- 2-3 tablespoons of buttermilk or lemon juice (for souring)
- A clean, sterile jar with a lid
- A thermometer (optional, but helpful for precise temperature control)
Step-by-Step Guide: Making Old Fashioned Buttermilk
Souring the Milk
The first step in making buttermilk is to sour the milk. This can be done using either store-bought buttermilk or a combination of lemon juice and milk. Here's how:
- Heat the milk to 180°F (82°C). This step is optional but helps to denature the proteins in the milk, giving the buttermilk a thicker consistency.
- Let the milk cool to 70-75°F (21-24°C). This is the ideal temperature range for the cultures in the buttermilk or lemon juice to activate.
- Stir in 2-3 tablespoons of buttermilk or the juice of one lemon. If using lemon juice, you may need to add a pinch of salt to mimic the saltiness of buttermilk.
Culturing the Milk
Once the milk is soured, it's time to let the cultures do their work. Here's how:
- Pour the soured milk into a clean, sterile jar.
- Cover the jar with a clean cloth or a loose lid to allow air to circulate.
- Let the jar sit undisturbed in a warm place (around 70°F or 21°C) for 12-24 hours. The exact time will depend on the temperature and the acidity of the milk.
The milk should thicken and develop a tangy flavor. If it doesn't, you may need to let it culture for a bit longer. Once it reaches your desired level of tanginess, it's ready to use or store.

Storing Old Fashioned Buttermilk
To store your homemade buttermilk, simply transfer it to an airtight container and refrigerate. It should keep for up to a week. You can also freeze it for up to three months. Remember, the longer it sits, the tangier it will become.
Culinary Uses of Buttermilk
Buttermilk is a versatile ingredient with a unique flavor that can elevate many dishes. Here are a few ways to use your homemade buttermilk:
- Drink it straight up, chilled, for a refreshing beverage.
- Use it in baking for a tender, moist crumb. It's particularly good in pancakes, biscuits, and cakes.
- Make buttermilk dressing for your salads.
- Marinate meats in buttermilk for a tender, flavorful result.
Making old fashioned buttermilk is not only a rewarding process but also a delicious one. So, why not give it a try? Your taste buds will thank you!
