Unlock the Secrets of Cultured Condiments & The Magic of Fermentation! ✨

Condiments hold a special place in every kitchen. On average, a person in the UK consumes over 2.5 kilograms of ketchup alone per year!

But what if we told you that adding fermentation brings a whole new level of flavour and health benefits?

Why Fermented Condiments Are Better:

Boosted Probiotics – Good bacteria that support gut health!

Enhanced Flavour – Rich, complex, and savoury taste profiles.

Increased Shelf Life – No need for preservatives or artificial ingredients.

Natural Health Benefits – Supports digestion and strengthens immunity.

Creative Possibilities – Ferment your way to unique condiments that stand out!

Join our Cultured Condiments Class to learn how to transform your favourite condiments into tangy, health-boosting, probiotic-packed creations.

Join us on:

The dairy aisle - an inspiration.

Every time I find myself in the dairy aisle, I only get milk and some inspiration.

Once you understand the principles and fall into the routine of making regularly,

• Yoghurt
• Cultured butter
• Milk kefir
• Fresh cottage cheese
• Labneh

it builds so naturally into your life, giving freedom of choosing your own quality, flavours, and unique taste.

Most of your dairy becomes fermented and so much healthier. So yummy!

At our Cultured Dairy Workshop, you'll learn how simple the traditional dairy fermentation really is.

During the class we'll:
🧀 Watch a live cottage cheese demonstration (and taste it fresh!)
🥛 Make your own milk kefir
🧈 Churn cultured butter
🥄 Taste a selection of cultured dairy products
📖 Learn how to recreate everything at home

You'll leave with your own kefir starter, yoghurt starter and freshly made cultured butter.

📅 Saturday 2 August
🕐 1–4 pm
📍 The Mill Community Centre, Walthamstow

If you've ever wanted to make your own cultured dairy, this class is for you.

Are you making these mistakes when brewing kombucha?

❌ not using starter for the 1st ferment
❌ putting SCOBY in the fridge
❌ assuming new SCOBY formation is mold

Mistakes are just experience, but most of them are incredibly easy to avoid even for complete beginners.
You just need to understand what's happening inside the jar and what you need to do (not much) in order to keep your kombucha SCOBY healthy, so it is making you a tasty drink.

Our Kombucha Brewing workshop covers:
✔️ Kombucha brewing basics (first ferment and second ferment)
✔️ How to know when it's ready
✔️ How to create natural fizz
✔️ How to troubleshoot common problems
✔️ How to keep your SCOBY healthy for years
✔️ How to take a break from brewing

Understanding some basics makes fermenting delicious drink so much easier.

Our experienced tutor Anna has been making kombucha at home for her family and at various London cafes for their menu for over 10 years.

She is teaching kombucha fermentation with us for around 9 years. And she is providing free ongoing support for our customers after the class in our dedicated facebook group.
