Calculating Correct Water Temperature

The following is an example of how to calculate the correct water temperature to use. You must

use your own room temperature, dry mix temperature, desired batter temperature, and, if you are making yeast-raised donuts, estimated temperature increase during mixing.

	Cake Donuts						Yeast-Raised Donuts
			°F			°C			°F			°C
Room temperature	72			22.2			72			22.2
Dry mix temperature			+70	+21.1					+70	+21.1
Total A	142			43.3			142			43.3
Desired batter temperature	75			23.9			80			26.7
Total B			x3			x3			x3			x3
	225			71.7			240			80.1
Total B	225			71.7			240			80.1
-Total A		-142			-43.3		-142			-43.3
Desired water temp. for cake donuts		83°F		28.4°C			98			36.8
									↓			↓
				Figure from above			98			36.8
Temperature increase during mixing (average: 30°F/17°C)								-30			-17
Desired water temperature for yeast-raised donuts								68°F		19.8°C

Ratios of Plunger Sizes to Donut Weights

The weights given are for donuts without icings or other toppings. They are provided for reference only, as weights vary according to the density of the batter.

Plunger Size	Donut Weight per
	Dozen
1”	5-8 oz/142-227 g
1 7/16”	10-17 oz/283-482 g
1 9/16”	14-21 oz/397-595 g
1 13/16”	19-23 oz/539-652 g

Temperature Conversion

To convert temperatures from Fahrenheit to Celsius, subtract 32 from °F and divide the result by 1.8. For example, 212°F-32/1.8 = 100°C.

To convert temperatures from Celsius to Fahrenheit, multiply °C by 1.8 and add 32 to the result. For example, (100°C x 1.8) + 32 = 212°F.

°F	°C	°F	°C
55	12.8	340	171.1
60	15.6	345	173.9
65	18.3	350	176.7
70	21.2	355	179.4
75	23.9	360	182.2
80	26.7	365	185.0
325	162.8	370	187.8
330	165.6	375	190.6
335	168.3	380	193.3
