Instructions
Buy the maximum amount of material each day you play. You may slightly overspend by buying too much for the day, but you will lose much more money if you run out of material part of the way through a day.
Open up the "Recipe" tab in the "Preparation" menu that appears at the beginning of every day. Look at the three tabs available: the coffee tab on top, the milk tab in the middle and the sugar tab on the bottom.
Left click on the "Coffee" tab and slide it to the right to make your coffee stronger. Stop at about 3 teaspoons to 3.5 teaspoons. This creates a strong blend coffee that isn't too strong for the average customer.
Drag your "Milk" tab to about 1.3. Leave it here to help blend milk with your coffee at a slightly under even rate. Add this much milk to smooth the taste of the coffee for the average customer.
Click and drag the "Sugar" tab to about 2.8 to make your coffee sweet. This drink will appeal to a wider range of potential buyers.
Find the "Price" tab underneath the recipe tab and drag it to about $2 or $2.50. Increase the price of your coffee as the week progresses to make more money via word of mouth customers.
