Picture the bins behind your bar at the end of a busy shift. Overflowing with citrus peels, bruised berries, spent herbs... It's a sad reality that the bar industry generates a massive amount of food waste. But what if those scraps held untapped potential – not just for your compost pile, but for your cocktails?
That's where enzymes come in. These tiny biological marvels have the power to unlock a world of hidden flavors, increase your ingredient yield, and make your bartending practices more sustainable. Let's dive into how it works, focusing on two superstar enzymes: pectinase and cellulase.
What Are Enzymes?
Enzymes are essentially nature's catalysts. They're proteins that speed up specific chemical reactions without being used up themselves. Think of them as microscopic tools that can build or break down various molecules.
How They Work
Plants have sturdy cell walls made up of substances like pectin and cellulose. These give fruits and vegetables their structure but also trap a lot of juice and flavorful compounds inside. Pectinase and cellulase enzymes target these specific cell wall components, breaking them down and making it easier to get all the goodness out.
Benefits Beyond Yield
Enhanced Flavor: Enzymes help release aroma compounds that might be inaccessible through traditional juicing.
Improved Texture: You often get a smoother, less pulpy juice, especially with fibrous ingredients.
Unique Possibilities: Using enzyme-assisted techniques can unlock flavors typically discarded, like extracting juice from pineapple skin!
Pineapple Power-Up: A Step-by-Step Guide
Why Pineapple?
Pineapple is a fantastic example of how much flavor we toss away. The sweet, juicy flesh is what we're used to, but the core and skin are packed with complex tartness, tropical notes, and a hint of spice.
Enzyme + Pineapple skin Prep
Choosing Your Enzymes: Look for powdered pectinase and cellulase intended for food or beverage use. (We'll discuss where to buy these later)
Calculating the 2% Solution: This means using 2 grams of each of the enzyme powders for every 100 ml of water. A kitchen scale is helpful!
Dissolve Completely: Stir the enzyme powder into room-temperature water until no visible particles remain.
Enzyme Magic: Combine the pineapple skins with your prepared enzyme solution in a vacuum bag. Try to remove as much air from the bag as possible before securely sealing it.
Sous Vide: Submerge the sealed bag in a precisely controlled water bath set to 55°C (131°F) and cook for 2 hours. If you don't have a sous vide device, you can improvise by placing the bag in a heat-safe container filled with hot water. But be extra careful to monitor the temperature, making sure it stays around 55°C (131°F) the entire time.
Straining: Once the cooking time is complete, carefully remove the bag and let it cool slightly. Reserve juice, and strain out the pineapple solids.
Crafting a Pineapple Cordial
Quantifying the Yield: To create a consistent and shelf-stable cordial, it's crucial to accurately measure the volume of the extracted pineapple juice. This measurement serves as the basis for the following steps in the cordial-making process.
Sweetener Incorporation: To achieve a well-balanced flavor profile, we will add 50% of the juice water in sugar. For example, if you yield 100g of juice, add 50 grams of sugar. Dissolve the sugar completely in the juice by stirring diligently. Once fully dissolved, remeasure the total volume, as the sugar will add to the overall liquid quantity.
Preservation and Acidity Adjustment: Based on the final volume of your flavorful liquid, add 10% of that volume in ascorbic acid and 5% in citric acid. These ingredients serve a dual purpose: Ascorbic acid, also known as vitamin C, acts as a preservative to extend the shelf life of your homemade cordial. Citric acid helps to balance the sweetness of the pineapple and enhance the tartness, contributing to a more complex flavor profile.
Pineapple Gimlet
Now, let's put that vibrant cordial to good use! Here's the recipe for a unique twist on the classic gimlet:
Ingredients:
60ml Gin (London Dry style works well, but experiment!)
30ml Pineapple Skin Cordial
Instructions:
Add the ingredients to a shaker filled with ice.
Shake vigorously until well-chilled.
Fine strain into a pre-chilled coupette glass.
Garnish with a lime wedge.
From Lab to Your Glass
This exploration of enzymes highlights just how much potential lies within ingredients we often overlook. You can elevate your cocktails, reduce waste, and create truly unique flavor experiences with these techniques.
Beyond Pineapple
Enzymes have applications with countless fruits, vegetables, and even spent botanicals. Experiment and see what flavor treasures you can unlock!
Where to Find the Right Tools
Choosing quality enzymes and acids is crucial. I've had great success with the brewing and winemaking products from TouFood ([https://www.toufood.com/?lang=en]). Their selection is geared towards small-batch use, and their customer support is excellent if you have questions. (It's important to note that this is my honest recommendation, not a sponsored endorsement.)
The Takeaway
Enzymes offer a fascinating way to push the boundaries of cocktail creation and sustainability behind the bar. I encourage you to try this yourself and let me know what amazing concoctions you discover!
