Question 1

What are quark's POD and PAC in gelato?

Accepted Answer

Low. Quark's only sugar is lactose (~3.6%), giving a sweetening power (POD) near 0.58 and an anti-freeze power (PAC) near 3.6 per 100 g, relative to sucrose at 100. It barely sweetens or softens the mix, so you must build sweetness and PAC with added sugars.

Question 2

How much fat and protein does quark add?

Accepted Answer

Full-fat table quark (Speisequark, 40% fat-in-dry-matter) has about 10 g fat and 9-10 g protein per 100 g, with roughly 24% total solids and 76% water. It is prized for high protein, which binds water and builds body and creaminess.

Question 3

Can quark cause a sandy texture?

Accepted Answer

Yes, indirectly. Quark is about 14% milk-solids-not-fat, so it raises total-mix MSNF and lactose quickly. Above roughly 10-11% MSNF in the finished mix, lactose can crystallize during storage and create a gritty, sandy defect. Dose accordingly.

Question 4

How is quark different from cream cheese or ricotta?

Accepted Answer

Quark is acid-set and drained but leaner and higher in protein than cream cheese, with less fat and a fresher, tangier taste. Unlike ricotta, which is made from whey, quark is made from the milk (casein) curd, giving a smoother, more spreadable body.

Question 5

Does quark replace milk or cream in a base?

Accepted Answer

Neither fully. Quark is a flavor-and-body ingredient, not a primary liquid: it carries fat, protein, and tang but little free water. Add it on top of a balanced milk-and-cream base, then re-check fat, MSNF, and total solids since quark shifts all three.

Parameter	Value	What it means
Total Solids	24%	Everything that isn't water — the backbone of body and scoopability.
Water	76%	Free water that will freeze; drives ice-crystal size.
Sugars	0%	Total sugars, the source of sweetness and freezing-point depression.
Fat	10%	Carries flavor and gives a rounder, warmer mouthfeel.
MSNF	14%	Milk solids-non-fat: proteins and lactose that stabilize structure.
Protein	9.5%	Binds water and helps whip in air.
POD (sweetening power)	0.58	Relative sweetness vs sucrose = 100.
PAC (anti-freezing power)	3.6	Freezing-point depression vs sucrose = 100 — controls how soft it scoops.
