A method of modulating the flavour of an orally-receivable product, such as a foodstuff, beverage, dentifrice or medicine, comprising the addition thereto of a flavour-modulating proportion of at least one compound of the formula I in which X is selected from CHOH, C=O, CH2-CO and CH=C(OH), Y is selected from C1-C7 linear and branched alkyl and CH2CH2OH, Z is selected from CH3 and a moiety of the formula II in which the wavy bond represents bond linking Z to X and R1 and R2 are selected from the possibilities (i) both hydrogen; (ii) independently OH and OCH3; and (iii) R1 and R2 together with their bonds to the phenyl ring form a ring of the formula -0-CH2-O-; such that, when Z is CH3, X is C=O and Y is CH2CH2OH
