Unfortunately, not all episodes of this series are available for viewing on the youtube. But the final episode is up in three parts and it's a fascinating one.
There is an absolutely ingenious method of saving fuel and space while cooking food, that starts around the 3:48 mark. I'm dying to try it out. I love the idea of tying food to the lid of a steam pot! And if you look carefully you'll notice that Ruth takes her tea saucer to use as a cover for the bowl of gravy that gets heated up in the bottom of the pot. Clever!
At 8:20 there's foraging for elderflowers and using them in pancakes.
Be warned that the second part contains a very graphic skinning of a rabbit. But the 'waste nothing' message at the 6 minute mark is valuable and relevant today. Although if I were Ruth I'd reserve the bean water she pours out for a soup stock, to water plants or at the very least put into the compost. Tsk tsk Ruth for pouring it down the drain!
I think the discussion of black markets 8 minutes in, is important and useful too.
Part 3 three is all about community and celebrations and sharing what you have, however little, with others.
