I’ve experienced both an American and English BBQ, these are my opinions on them…

ENGLISH BBQ
An English BBQ, relaxing in the back garden, a beer or glass of Pimms, talking with a few family members as one person looks after the grill, turning the sausages and burgers over at regular intervals
Big buns, a proper handful. The atmosphere leaves you relaxed and slowly falling asleep with a full belly…
AMERICAN BBQ
An American BBQ is an event. The BBQ I went to in April had more food then you could imagine and is an event for the whole family, mothers, brothers, fathers and cousins. If I remember correctly there were 32 burgers in total and a wave of hot dogs.
Ending off with a nice game of catch… I ate way too much…
