Why Learn to Preserve?

Whether you really need all the fancy equipment or whether you can preserve on a shoe-string budget…

That’s exactly why we created our beginner-friendly online preserving course to help you get started with confidence — without the stress or second-guessing:

Your presenter, As Seen on Seven Sharp…

Many of us who grew up with ‘preserving’ mum’s, aunts or grandmothers are enjoying their legacy today. So grateful for what you share, your legacy. You are an angel. (I look forward to learning how to preserve cooked potatoes!)
Robyn McQueen

I remember both my Grandma and my Mum preserving bottling and making jam jelly and chutney. Thank you so much for sharing such a precious recipe (one of the bonuses) I have just read it and feel that even I might be able to make…watch this space and once again thanks!

Thanks for sharing your beloved recipes with us Katherine. I’ve been following your Facebook page for awhile now. Like you I grew up with ‘preserving’ grandmothers and mums.
We have our own small orchard and I like nothing better than picking & preserving what we grow. Full jars in the pantry are the best!

who is this course for?

The Budget-Wise Gardener

You’ve spent years growing your own food and want to minimise waste. You’re living on a shoestring (or just love a good bargain), & you’re looking for safe, affordable ways to preserve your harvest without overwhelm.

The Practical Provider

You’re feeding a family and want to know exactly what’s in your food. You’re focused on reducing waste, cutting grocery costs, and building food security — with easy, step-by-step guidance that fits your busy lifestyle.

The Cautious Newbie

You’re new to canning and preserving and want to get it right. You’ve read too many conflicting articles and feel nervous about safety — so you’re looking for simple, trusted advice from someone who actually knows their stuff.

The Self-Reliant Soul

You love the idea of stocking your shelves with homemade goodness — not just for the satisfaction, but for the security. Whether on a budget or loving DIY, you want simple, step-by-step guidance & skills you can rely on for years to come.

“I absolutely loved all of Katherine’s practical tips – you can tell she’s been doing this for years. Her teaching style is so laid-back and down-to-earth, it made the whole process feel doable and fun. I followed along with the video and made the jam step-by-step, which really helped me as a hands-on learner. I have to do it to learn it, and this course was perfect for that.”

FAQS

Water bath canning is used for high-acid foods like fruit, jams, and sauces, while pressure canning is needed for low-acid foods like vegetables, meats, and broth. In the course, we clearly explain when to use each method — and why it matters for safety.

Not at all. We show you how to start with just the essentials — many of which you may already have at home. You’ll also get honest advice on what’s worth investing in and what you can skip.

We understand! Many beginners are nervous about safety, especially when it comes to botulism or spoilage. That’s why both courses focus heavily on safe, proven methods and include clear steps so you know exactly what to do — and what not to.

Yes, you absolutely can. These courses are made for beginners — even if you’ve never picked up a preserving jar or pressure canner before. You’ll get the support, structure, and confidence to start right where you are. And you won’t be doing it alone — we offer email support if you get stuck, plus access to our active Facebook community where you can ask questions, share your progress, and learn alongside others.

You’ll have lifetime access to all lessons, resources, and updates. So whether you want to follow along now or come back during preserving season, the course is always here for you.

Yes — while Katherine teaches from New Zealand, all the techniques are based on internationally recognised standards (like USDA guidelines), and are applicable no matter where you live.
