Food Unwrapped Season 12

E1: Marmite, Plastic, Custard

Jimmy examines how plastic packaging is polluting the food chain with potentially global implications. Is it really possible to predict if you'll love or hate Marmite? Matt runs across a custard pond.

Jimmy learns about the battle against the hidden nuisance that leads to corked wine. Plus: the surprising difference between runny and set honey. And okra.

E4: Whisky, Halloumi, Sweetcorn
