Wow, you got a basket! This means that you can now increase the amount you can buy at a time before restocking.
Head to the market to upgrade your ingredients.
To upgrade your ingredient:
tap on the market
tap on upgrade - this is on the left-hand side of the screen
select which ingredient you would like to upgrade, it will tell you how many baskets you have and how many you need to upgrade a certain ingredient here as well.
Done no more waiting :-)
Quick tip:
Baskets are given to you when leveling up on certain levels of the game, and now you can find them in some of your Wholesale delivery crates.
Please note!
The baskets are used to give you another chance to buy the upgraded ingredient before getting a timed cooldown. Each of those tries has an individual cooldown. This means that if you wait long enough you get all your tries back.
You can actually see in the market that the various circles symbolising your tries slowly fill up. Only when a circle is filled up you can purchase the related ingredient once.
