How to use Angostura bitters?

Angostura bitters can be used in many ways, not just to enhance flavors in alcoholic drinks.

Angostura bitters in a cocktail

You can use it as:

  1. Cocktail ingredient
  2. Garnish for cocktails
  3. Marinades and sauces
  4. Cooking with Angostura bitters

1. Mixing Angostura bitters as an ingredient in cocktails

The most common way to use aromatic bitters is as a flavor enhancer in cocktails. For this, a few drops or dashes are added to the other ingredients while measuring. This way, the overall complexity of flavors is increased, leading to a deeper flavor.

One of the first recipes and most popular drinks mixed with Ango bitters is Pink Gin, a combination of Plymouth Gin and said bitters. Later, classics like the Old Fashioned, Vieux Carré, and Manhattan cocktails ensured every bartender had a bottle of Angostura handy.

If you want to try an Angostura bitter-forward cocktail, try a Trinidad Sour. The recipe doesn't use a few drops of Angostura bitters. No, it demands a whopping 1.5 oz. -A flavor bomb that's certainly not for everybody.

2. Use Angostura Bitters as Cocktail Garnish

Using a few drops of Angostura bitters on the foam of cocktails is another amazing way to use the bitters.

Many classic cocktails like Pisco Sour, Whiskey Sour, and Mezcal Sour use these elegant bitters garnish on top of egg white or aquafaba foam. That makes the drinks smell more fragrant and complex, which ultimately also alters the flavor profile of the drink.

3. Use Bitters in Sauces and Marinades

With its savory taste and alcohol content, Angostura bitters can enhance marinades and sauces by adding flavor and softening meat. Yet, when adding alcoholic ingredients to marinades, there's a risk of overpowering flavors. 

While vodka, being tasteless, doesn't pose a problem, wines, rum, or bitters should be used cautiously. Many bitters-based marinade recipes include ingredients like citrus, garlic, or soy sauce to balance flavors. 

Avoid over-marinating to prevent undesirable textures and colors, and ensure thorough cooking to eliminate alcohol-related aftertastes.

4. Cooking with Angostura bitters

Besides marinades or sauces, there are many more ways you can use Angostura bitters for cooking.

Cooking with Angostura bitters brings a slice of the Caribbean to the kitchen, even when physical travel isn't an option. This flavorful ingredient, known for its role in cocktails, such as the classic Manhattan, holds a special place in the heart of West Indian cuisine. 

In rich and flavorful dishes like a West Indies Shepherd's Pie, the bitters work their magic by harmonizing with ingredients like lime zest, scallions, and habaneros, intensifying their flavors. To achieve a balanced and rich profile, it's best to incorporate bitters early in the cooking process, allowing their penetrating essence to meld seamlessly with other components. 

Other Popular Bitters 

Besides classic aromatic bitters like Angostura or Peychaud's bitters, new brands develop more fine-tuned infusions like celery, chocolate, and orange bitters.

Here are some popular brands and products and how you can use them to balance the harshness of spirits and add a layer of complexity to your cocktails.

  • Peychaud's Bitters: The flavor profile of Peychaud’s bitters is sweeter, with distinct notes of anise and mint. These bitters are key to some classic drink recipes, like when making a Sazerac cocktail.
  • Orange bitters: Orange bitters have an intense orange taste derived from essential oils from orange peels. They're quite common, and even Angostura produces its own product called Angostura Orange.
  • Chocolate bitters: Chocolate-flavored bitters have a distinct dark chocolate flavor and are delicious bitters in Old Fashioned cocktails.
  • Celery bitters: Celery bitters are just one example of modern, specialized cocktail bitters. These kinds of bitters are great in a Martini to enhance the flavor of other ingredients in the drink. 
  • Lavender bitters: Another prime example of bitters, these floral bitters are excellent in a Gin and Tonic. They balance the harshness of acidic contents and bring a flowery touch to your drink.

The bitters are not only known for their complex taste but also their visual appearance. The big and oversized label is one of the striking visuals that makes this brand so memorable.
