We used to keep poultry and sheep and swap lamb for friends' pork . So now we buy meat, we're still fussy about the quality and provenance ; all British raised. I'd rather eat smaller amounts of high quality meat, than a bigger helping of poor quality but cheaper.
The same for some fruit ; I only buy tasty fresh Scottish strawberries and raspberries, which means we only eat them seasonally. I've no interest in tasteless winter imports.
I grow a lot of vegetables and fruit, and we eat a lot of this home produce fresh and seasonally too; there is nothing like your own baby potatoes, asparagus, runner beans, peas, herbs, strawberries, blue berries,broadbeans picked at their peak, fresh straight from the plant. to the pan or plate. At this end of winter, I still have fresh leeks, kale and herbs in the ground.
We crop so many plums and tomatoes I have to freeze lots ( tomatoes made into sauce then frozen)
I still swap garden produce. now with a generous neighbour who harvests a secret source of wild chanterelles. His wife makes a lot of jam and chutney from our plums ( so I don't have to).
DH has handmade all our breads for the last 50 years; sourdough and yeasts. He also bakes great cakes ( so i don't have to bake. ).
Veg garden has spent winter under a thick mulch of sea weed; new seasons broad beans are 4 leaves high. Potatoes are chitting, just collected a car load of horse manure to compost ; washed the greenhouse and bought new seeds.
New season at the allotment is ready set to go go go
