The McRib is back. I actually have no idea what a McRib is, but it's back, and it's apparently one of the fast food chain's most commonly requested limited menu items. So we've picked one up, tasted it and, more importantly, seen how it stacks up to its glossy (and saucy) promotional imaging. Here's our verdict.

Lifehacker has indulged in some highly unorthodox taste tests over the years. From bacon milkshakes to placenta pizza, we've stuck a lot of weird and horrifying things into our mouths. To round off Friday, here are ten of the grossest gastronomical nightmares to squelch into our office. (You might want to read this one on an empty stomach.)

There are few things KFC customers love more than Hot & Spicy chicken - and the Colonel is finally beginning to capitalise on this fact. This year, the company launched its first offshoot product in the form of Hot & Spicy Chicken Nuggets. Now, its infusing that famous fiery flavour into its popcorn chicken range. At least, that's the idea in theory. Read on for our taste verdict.

BBQ Shapes are the best flavour of Shapes, no question. (Don't @ me.) So it only makes sense to add that delicious fake BBQ flavour to other delicious foodstuffs, right? For the next three weeks, Deliveroo is offering three unique BBQ Shapes inspired dishes in conjunction with Arnott's, and we've tried one of the offerings. Here's what we think.

Coffee and energy drinks are a staple part of my diet. Despite this, I tend to roll my eyes at special edition flavours of energy drinks. The Coconut Edition Red Bull didn't seem like something I would enjoy so I bought some to find out for sure.

The KFC Zinger Double Down King is an "all meat" burger comprising cheese, bacon and a beef patty sandwiched between two KFC breast fillets. In other words, it takes the OTT concept of the KFC Double and elevates it to ludicrous proportions.

Tragically, the Double Down King isn't available in Australia, but don't let that stop you from sampling its colon-clogging delights - as the following taste test demonstrates, it's possible to build your own. The results are spectacular... and probably a bit lethal.

Mad Mex is going full vegan, with dairy- and lactose-free cheese now available at all Australian restaurants. (Best of all, it's currently free to add to any menu product.)

Mad Mex swears on the eyes of orphan children that its new product looks like real cheese, tastes like real cheese and melts like real cheese. We conducted a blind taste test to uncover the truth.

Takeaway Truth is an occasional Lifehacker feature where we compare marketing images against what you actually get served. Today: McDonald's Big Brekkie Burger. (Plus taste test!)

It's taken an incredibly long time, but KFC is finally selling Hot & Spicy chicken in nugg form! We sampled this limited-edition menu item yesterday. Read on for our verdict.

As part of a promotion run by The Economist, a pop-up ice-cream stall opened in Martin Place for the day, right near our offices in Sydney. Awesome! I love ice cream! I'll go check it out, I said. The catch? The ice-cream was filled with insects. I was already in too deep to back out.

Now you, dear reader, get to experience what it is like to fill your mouth with dairy and dirt-dwellers. Hakuna Matata.

We were invited to KFC's flagship store in Mascot NSW to see how the company makes its chicken first-hand. We were shown every step of the process; from how meat is stored and prepared to the various ways KFC keeps its "secret" herbs and spices out of the hands of suppliers. Read on for a full kitchen tour.

In 1923, Cyril P. Callister invented Vegemite. 94 years later, we have Vegemite: Blend 17.

It's the ultimate junk food face-off! In the red corner: a Maple-glazed fried doughnut. In the blue corer: a big, fat slice of New York-style pizza. There can only be one winner.

Today, Coca-Cola launched Coca-Cola No Sugar in Australia - a new diet version of its popular soft drink that purports to taste much better than Coke Zero. We'll be the judge of that.

Yesterday KFC sent us a ridiculous four buckets of their latest chicken -- which is reportedly marinated in Tabasco for 24 hours. We ate a lot of it.

Here's what we thought.
