Oh no no, definitely not as good to pop it in all at once. You get so much less out of the experience. Whether you suck out the cream or not, it's best to take it in bites
As an American in London a few summers ago, I found it very wierd to be able to buy a Cadbury egg in mid-July. It just wasn't right. Plus, it melted a bit which just made it worse.
You can find them around Southern Ontario at various times through-out the year as well, despite what the commercials say.
I usually just bite the top off first and then finish it with another two bites or so. The trick is to savour the bites, not how big/small the bites are.
Rob's technique I reserve for other things. Minus the hoover sounds
Why did they make it seasonal in the States? Mind you, easter eggs here have the same problem, I guess. In my professional opinion all forms of chocolate should be available all the time:)
I bite off the top then nibble down as far as possible before contents splurge then munch the last bit!
It used to be seasonal in the UK, too (or at least in England). I dimly remember when they extended the season to run all the way from Advent to Easter, instead of just being Advent and Lent. Or something like that.
