Caterers and chefs will often have to work in commercial kitchens, working around other members of kitchen staff and using the equipment that is available there. This can pose significant challenges, even affecting the quality of your work if you find yourself without the means of cooking and preparing food in the way you would like.
It might be a good plan to have lots of your own portable catering equipment to use, as this will mean you always have equipment you like and that you are familiar with. You can buy lots of good quality catering equipment online that will serve you very well in your professional life, so you can take it with you to all of your jobs. Smaller items like blenders, utensils and crockery can easily be transported to your venues, and having them with you will give you more confidence that you can produce food to a consistently high standard.
