Welsh for a week eating challenge

By Hywel Griffith BBC Wales' health correspondent

Day One: No bananas Day Two: Spice of life

Day Three: Into the wilds

Having grown up in rural West Wales, I thought I knew my way around the countryside but after yesterday's a trip to the forest with Yun Hider, I feel like a real city boy.

Yun is a professional forager from Pembrokeshire with 10 years experience of sourcing wild food.

As part of eating Welsh for a week, he's agreed to take me on a culinary tour in the Gower with Brice family, who've joined me in the challenge.

Yun sets off with huge enthusiasm, and soon he's getting us to taste blackberry leaves, flower petals and hairy bitter cress. He thinks it's a shame our knowledge of natural plant life is being lost. "It's a knowledge that is out there still, but is becoming less, that's a fact", says Yun.

"The simple art of collecting blackberries for example - people are forgetting that you don't have to go to the supermarket to find yourself a really delicious fruit.

"There are ones literally growing in your garden or in the hedgerow down the lane."

The Brices seem to be enjoying our tasting session - although a few of things seem are too bitter for six year old Jacob, who ends up spitting out his blackberry leaves.

However, a trip down to the stream brings a fantastic find - wood sorrel. It's a heart shaped leaf a bit like clover, that grows near trees.

I'd never seen or tried it before, but its really sweet and lemony and I'm an instant convert - as is six year old Jacob, who grabs a load to take to his parents.

Inspired by Yun, I've come up with some sort of coffee replacement for the week. I've started making my own tea with mint leaves from the garden.

It's a bit of an ad-hoc experiment, but I'm starting to get the hang of it. I've even started bringing a few mint leaves into work - it gets a few strange looks from my colleagues, but at least I know its Welsh - and free!
