Totally dedicated to learning everything they could about cheese - be it through experts, magazines or even foreign books - in 1934, the three siblings founded Lacticínios MAF, Lda., a name that came about from the junction of their initials. They immediately began producing the Flamengo cheese ball, unknown to Portugal until then. That same year, they registered the Rico brand, using the Feira Castle as a symbol on the packaging, a brand image that remains to this day.
