Cook’s notes
- Milk thickened with cornflour freezes without splitting; add a spoon of crème fraîche at serving for extra richness.
- For a pie, defrost 8 blocks in a dish, top with puff pastry and bake at 200°C for 30 minutes.
- Brown the mushrooms well so they don't go watery.

Creamy Chicken & Mushroom questions
Can I use chicken breast instead of thighs?
Breast works but dries out more easily. Brown it briefly and cut the simmer to about 10 minutes so it stays tender.
Can I add bacon?
A little smoked bacon goes well with chicken and mushroom. Fry about 100g of diced bacon or lardons with the chicken, then season more lightly at the end, as the bacon adds salt.
Can I make it with a dairy-free milk?
Unsweetened oat milk thickens with the cornflour in the same way. Avoid sweetened or flavoured versions, which will show in the sauce.
