Well of course crème anglaise is ubiquitous in French pastries but it would still be odd to call a dish ‘tarte aux fraises’ and label it a signature British dish just as it would with crème brûlée or tiramisu. There are plenty of English variants and names for the same/similar things that would make the concept work though!
