They need to quit with the crap, just go back to seasons 1, 2 & 3 and re-use the damn challenges. They were good for skill evaluation, made sense and had enough creativity. Except for Paul, the judges and hosts are all different. It would be fine.
I've seen a show where they made "hand pies", but don't know if it was this one. Pastie, hand pie or whatever else they call it, it's a good challenge. But for my tastes, the savory ones need to be served hot. The fruit or sweet ones, like turnovers I like fine room temp.
I didn't see any actual Key limes on Laura's workstation, but she could have used a good quality bottled Key lime juice. Several good brands are easy to mail order if they can't find it locally. I can't see them getting fresh Key limes in for just that one challenge. One bad lime and her tart is toast. You can get bottled Nellie & Joes almost everywhere.
