Useful guidelines

Feeding your Starter

Our Starter is fed 100% Wholemeal Flour, this is to give the bread more flavour as the flour contains the wholegrain. You can use white flour or any other grain you prefer. The best flour for starting end feeding would be rye due to its high nutrient content and levels of naturally present lactobacilli.

 

Directions

Simply follow these steps in order to make Carrot Top Hemp Pesto

Step 1: Select Tender Carrot Greens

Carefully sort through the carrot tops and select only the tender green leaves. Remove any damaged, yellow, or wilted leaves. The youngest leaves will provide the freshest flavour and the best texture for your pesto.

Step 2: Prepare an Ice Bath

Fill a bowl with ice-cold water and set it aside. This ice bath will immediately stop the cooking process after blanching, helping the greens retain their vibrant green colour and fresh flavour.

Step 3: Boil Salted Water

Bring a small saucepan of water to a rolling boil.

Add 1 tablespoon of salt to the water. The salt seasons the greens lightly and helps preserve their bright colour during blanching.

Step 4: Blanch the Greens

Add the carrot tops to the boiling water.

Blanch for 3 to 5 minutes, or until the greens are softened and have turned a vivid green colour. Blanching helps reduce bitterness while creating a smoother, more balanced pesto.

Step 5: Shock in Cold Water

Using tongs or a slotted spoon, immediately transfer the blanched carrot tops into the prepared ice bath.

Allow them to cool completely. This step stops the cooking process instantly and helps lock in the beautiful green colour.

Step 6: Drain Thoroughly

Drain the cooled greens well.

Using your hands, squeeze out as much excess water as possible. Removing excess moisture is essential for creating a rich, flavourful pesto with a longer storage life and a better texture.

Step 7: Blend the Pesto

Place the blanched carrot tops, Parmesan cheese, hemp seeds, olive oil, and a pinch of salt into a blender or food processor.

Blend until a chunky pesto forms. Scrape down the sides as needed to ensure everything is evenly incorporated.

Taste and adjust the seasoning with additional salt if required.

Step 8: Transfer to a Jar

Spoon the finished pesto into a clean 200 ml (7 oz) glass jar.

Smooth the surface and, if desired, cover it with a thin layer of olive oil. This traditional technique helps reduce oxidation and keeps the pesto fresher for longer.

Step 9: Store

Seal the jar with a tight-fitting lid and refrigerate.

The carrot top pesto will keep in the refrigerator for up to 14 days. For longer storage, freeze in small portions using an ice cube tray and transfer the frozen cubes to a freezer-safe container.

Frequently asked questions

Are carrot tops edible?

Yes, carrot tops are completely edible and have been used in kitchens around the world for centuries. Although they are often discarded, the leafy greens are both nutritious and flavorful. Their fresh, herbal taste makes them an excellent addition to pestos, soups, sauces, stocks, and salads. Using carrot tops is also a wonderful way to reduce food waste and make the most of your harvest.

Why do you blanch carrot tops before making pesto?

Blanching helps soften the greens and reduces some of their natural bitterness. It also preserves their bright green color, resulting in a more vibrant pesto. While raw carrot tops can be used, blanching creates a smoother texture and a milder flavor that many people find more appealing.

What do carrot tops taste like?

Carrot tops have a fresh, herbaceous flavor similar to parsley, with subtle earthy notes and a slight bitterness. Younger carrot tops tend to be milder and more delicate, while older greens can have a stronger, more robust flavor. Their unique taste pairs beautifully with garlic, olive oil, nuts, seeds, and cheese.

Can I freeze carrot top pesto?

Absolutely. Carrot top pesto freezes very well and is an excellent way to preserve seasonal abundance. Spoon the pesto into ice cube trays and freeze until solid. Transfer the cubes to a freezer-safe container or bag and store them for several months. This allows you to thaw only the amount you need for a meal.

How long does carrot top pesto last in the refrigerator?

Stored in an airtight container in the refrigerator, carrot top pesto will keep for up to 14 days. To help maintain freshness and prevent oxidation, smooth the surface of the pesto and cover it with a thin layer of olive oil before sealing the jar.

Can I make this pesto without hemp seeds?

Yes. Hemp seeds provide a creamy texture and mild nutty flavor, but they can easily be replaced. Sunflower seeds, pumpkin seeds, walnuts, almonds, pine nuts, or cashews all work beautifully. Each alternative will create a slightly different flavor profile while still producing a delicious pesto.

Are carrot tops healthy?

Carrot tops contain a variety of vitamins, minerals, and beneficial plant compounds. They are a source of vitamin K, vitamin C, potassium, calcium, and antioxidants. Like many leafy greens, they can be a valuable addition to a balanced diet and offer a nutritious way to enjoy more of the vegetables you grow or purchase.

What can I use carrot top pesto for?

Carrot top pesto is incredibly versatile. Toss it with pasta, spread it on sandwiches and wraps, stir it into soups, spoon it over roasted vegetables, or serve it alongside grilled meats, fish, or eggs. It also makes a wonderful dip for fresh bread or a flavorful addition to grain bowls and salads.

Can I use carrot tops from store-bought carrots?

Yes, as long as the tops are fresh and vibrant green. Avoid tops that are yellowing, slimy, or wilted, as these may have lost much of their flavor and quality. Wash the greens thoroughly before using them, especially if they have been exposed to soil or stored for an extended period.

Why is my carrot top pesto bitter?

A slight bitterness is natural, particularly if the carrot tops are mature. Blanching the greens before blending helps reduce bitterness significantly. Adding enough olive oil, Parmesan cheese, and a touch of lemon juice can also help balance stronger flavors and create a more rounded pesto.

Can I make carrot top pesto vegan?

Yes. To make a vegan version, simply replace the Parmesan cheese with nutritional yeast, a vegan hard cheese alternative, or a mixture of nuts and nutritional yeast. The pesto will still have a rich, savory flavor while remaining completely plant-based.

Is carrot top pesto a good way to reduce food waste?

Absolutely. Carrot tops are one of the most commonly discarded edible vegetable greens. Transforming them into pesto is a simple and delicious way to use the entire plant rather than throwing away a valuable ingredient. It reflects traditional farm and kitchen practices where every part of the harvest was put to good use.
