Mayonese economics seems bit off.
Eggs base price is 1.5, vegetable oil base price is .65 and mayo bese price is 1.
Mayo takes 50 oil + 50 eggs to produce 50 mayo (this seems wrong)
So with 1000 mayo, you make 1000 euros.
But if you sell oil and eggs separately, you get 2150. So you make way more more money by not making mayo.
Suggestion,: make mayo machine make 100 litres of mayo from current ingredient amounts (which would also be logical), and mayo price should be slightly upmarked so making mayo would bring maybe 10-20% more money than just selling the base ingredients.
