The Food Lab: How To Make Beef Barbacoa Better Than Chipotle's

Making this for Cinco de Mayo. Is there any alternative to using a Dutch oven? I, strangely enough, live in Holland, but have no such apparatus (or an oven big enough to fit one).

DIY Orange Liqueur

I made this, but could only steep it for 1.5 weeks. There did seem to be a change in the last few days - the zest stopped floating, the oils inside settled quicker - that made me think it was getting close to being ready. I only added about half of the recommended sugar too. Since I'm using them in a margarita with simple syrup and fresh fruit, I didn't want to go too far into sugarland.

EAT THIS NOW!: Fried Pizza with Homemade Sausage, Egg, Parmesan, and Hollandaise

Wow, guys, unduly harsh. Can we concentrate on the fact that Kenji has FRIED A PIZZA? No I don't feel so bad that my only oven has the word 'microwave' before it.

Margarita variations for a street party

Hey all,
I'm looking for some tried-and-true variations of margaritas to sell at Queensday, the Netherlands' biggest street party*.

I'm looking to sell margaritas outside my apartment. Limes can be expensive and hard to come by in this neck of the woods, so I'm wondering if anyone has a variation that cuts down on them: lemons, oranges, other citrus.

For any bartenders out there, what's the standard amount of liquid given in a cocktail? I don't want to stiff the Dutchies.

Other cheap-n-easy variations on cocktails are welcome (cheap being important).

*There's no sales tax on that day, so everything turns into a massive yard sale. Sure, selling food or drink is technically not allowed, but everyone does it :)
