I know, the market of dessert tools is saturated with gadgets and gizmos. You'd almost become cross-eyed trying to find the right ones.
It helps writing down a list needed to complement the rest of the dessert equipment.
Not everything found at the warehouse should be part of your kitchen. Some tools are an absolute necessity. Others I would classify as luxury items. Find what you consider convenient.
If it helps you cut working time or when it helps make a process much easier, by all means, purchase those dessert tools. Especially when you're preparing to pursue something professionally.
Take your time to do a small inventory. Think about what would improve the workflow.
See the columns below as a general checklist for you to go through. It'll help to remember, or maybe there's something you didn't know existed.
The list of things to add to your kitchen arsenal is incredibly long.
Beginners could be tempted to buy all sorts of tools only to find later they're not using a good part.
Professional pastry chefs use most or all in the list, but it doesn't mean you have to own all of them too.
You probably already own some kitchen instruments, including pastry supplies like cling film or baking paper.
As time goes by and your interest or passion for dessert making is still there, you'd probably want to try out new recipes that are more technique-specific.
Perhaps something more exotic, more decorative, higher amounts, or maybe acquaintances/friends are asking to make something requiring less common dessert tools.
Only then consider expanding on the kitchen equipment.
If they pay you to make a birthday cake, grab the opportunity to do just that. Luckily most of us already have a toolset for general cooking, which includes dessert tools.
