The closest I've been to an actual African journey.
Flavor Name: Variety, Size: 2 Ounce (Pack of 5)
I've always wanted to trek to the high seas and down the Ivory Coast, making my way to South Africa. Alas, I have yet to have the chance. But with Brooklyn Biltong, I felt like I was part of that great adventure. From the moment the package arrived in the mail, I was excited to dive in. The three different colors of the packages was really enticing. Which flavor first - red, yellow, or blue!? I went with the original flavor first (red) to get a real sense of the product. As I opened up the package I was overwhelmed with the smells of air dried goodness, with a hint of coriander. With just enough bite, I went into paleo heaven. As a gym and health nut, this was the perfect treat after I blasted off reps of 350lbs. It gave me the energy I needed to really make my way through the day before hitting the club later than night with my bros. But how can we forget about the other flavors? Jo'burg steakhouse? O.M.G. I legit thought I was hanging with the late great Charlie Palmer nibbling down on some garlicy cow goodness. The Peri Peri BROUGHT. DA. HEAT. I felt like I was on trial with all that SPICE. This is the real deal. You don't need to go to Brooklyn to wear skinny jeans and you don't need to hop on a plane to South Africa to get the whole experience. Worth. Every. Bit. Of. My. Hard. Earned. Cash. DO IT.

So Delicious… but expensive!
Flavor Name: Variety, Size: 2 Ounce (Pack of 5)
Wow this stuff is delicious! I was prepared to be underwhelmed and I was so pleasantly surprised because it was so good. My favorite is the Peri Peri flavor, but they are all good. The price is so expensive, but since I’m restricting sugar right now, it was a thoughtful healthy splurge. Highly recommend for quality, flavor, and texture. But I might have to start a beef jerky savings fund to be able to afford to order more.

I am so glad this is availbe in the states now.
I first had Mr's Ball's in Southern Africa in 2006 while on Safari in Namibia and Botswana. It was so good I packed quite a few bottles to take home. It goes great with meat, cheese, on sandwiches, just a fantastic flavor. I'm now spoiled and can NOT buy any of the "usual" chutney's available to us in the States. So I keep well stocked now thanks to Amazon.

There so much flavor without it oozing all over the place.
I am so happy I found this chutney. It is perfect consistency to spread on bread to make our chutney sandwiches. The double bottle buy is the way to go. Always have one back up ready to go.
