Tubby Toms
Tubby Tom’s is the perfect combination of all of my passions. I spend all day working with amazing food, creating sauces and seasonings and selling them to awesome, like-minded people.
It all started with a single batch of BBQ sauce i’d made in the summer of 2014. My friends loved it and joked about how I should sell it and brand it as ‘Tubby Tom’s’. I thought it was pretty funny and it seemed like a great idea, so I made some more, drew up some sketchy labels and took it down to our local farm shop.
The weekends I didn’t spend cooking the sauce, i’d be out at farmers markets selling it. My friends and family often got roped in (common theme here) to help me do the big cooks. They also helped me with the market stalls sometimes too, they’re the best. Thanks guys, couldn’t have done it with out you.
Use as a Rub!
Choose your flavour destination, find the rub that is influenced by that location and then simply rub it on your food to take your cook to new levels and your taste buds to new places with ease.
Rubs go well on all foods, not just meat, and don’t just limit them to being used on the BBQ.
Use as a Paste!
Pick a flavour, find the rub that is influenced by that flavour and then most rubs can be mixed with either an oil such as sesame oil, olive oil, or you could choose to mix with a mayo, yoghurt, or even a vinegar. Its an endless list of possibilities and combinations for you to play with.
Use as a Marinade
Mix up a paste, add layers of flavours with your paste, leave your food to absorb the flavours for at least an hour, or even better over night.
