Since leaving the EU in January 2021, British travellers from England, Wales and Scotland face restrictions on food and drink items allowed into the EU.
POAO – products of animal origin (meat and dairy) are no longer allowed; this extends to cakes that contain fresh cream and confectionery "made with high levels of unprocessed dairy ingredients”.
You're still allowed to take powdered infant milk, infant food and foods needed for medical reasons; they must weigh less than 2kg and be packaged, branded products.
Vegetables and most fruits are also banned – bananas, coconuts, dates and pineapples are the exception.
If you're so inclined, you're allowed up to 20kg of fish.
"Products other than those described above which do not contain meat or milk (eg honey)” are limited to 2kg.
On your return to Blighty there are no significant changes. The UK government says: "You can bring meat, dairy [and] other animal products, for example, fish, eggs and honey.”
