It dawned on me today while using the spices that perhaps, just perhaps, I could dump a 10% additional servings spice on ONE dish, over and over and over and have it multiply it that many times on ONE dish, instead of doing it on 18 dishes that I was cooking.
So I tried it. I dumped the 10% spice on one serving of Mu Shai Dumplings that I was cooking 30 times. I think the dumplings are 580 servings per dish that you are cooking. I then used the 1-hour thyme on it 5 times - it's a 6 hour dish. I then started dumping the Mystery spice on it. Some of the Mystery spices are rather worthless. You get some that that take 2 minutes off of cooking time, or 5 minutes. Big waah. Waste of time for that. Some of them give you free gold coins or cafe points - semi-worth it.
Well, when this dish was done cooking there were almost 3,000 servings on that ONE dish. It does NOT, however, give you multiplied Cafe points, so this tip is only good for increasing the amount of dishes you can get off of a dish that you are cooking.
BTW, some people mistakingly believe that you have to pay cash for all of the spices to get more. True with 1, 6 and instant Thyme, NOT true with the 5% and 10% increase. You can buy those with gold coins.
So, today, I bought one dish of Chinese Candy. I am going to dump at least 100 10% spice on it before it's done cooking - it takes 2 days. That will give me a net of 20,000 servings off of ONE dish that is cooking on my stove!! If I have time, I will 200, but the spices are rather slow in applying them to a cooking dish, I don't want to spend too much time on this game. But let's do the math. To buy one serving of Chinese Candy is 6,000 gold coins for 2,000 servings. If you add the 10% spice, then each time you add the spice, you are getting 200 additional servings of the Candy.
I believe the Candy is 9 coins per serving. So, if I do 100 10% spices on it, giving me and extra 20,000 servings, multiplied by 9, that's 180,000 gold coins for that dish. A 100-pack of 10% spice is 60,000 gold coins, so my net profit by adding the spices to it is 120,000 gold coins plus the 2,000 for the original dish minus he 6,000 to buy it. Not a bad return, aye?
Finally, you can add the spices ANYTIME while a dish is cooking. If you have 1 minute left to cook, you can still add spice to it.
The obvious advantage of doing it this way is that you only tie up one stove. Unless you don't care about gaining Cafe points, you don't want to tie up all your stoves doing this. I do not like doing 2 day dishes because to get any amount of it, you have to use all of your stoves. But, with this method, I don't have to do that, will end up with as many servings as I want tied to how many spices I want to add to the dish, and I get a LOT of gold coins for it in the end.
