If you prefer to colour them red, tie up some cochineal in thin muslin bags.
Then add the pure of fruit, and a few drops of cochineal to colour it.
Several species also have been used in dyeing, especially the cochineal insect of Mexico, a species which lives on the cactus.
Colour with cochineal, and pour the mixture into a wetted mould.
cochineal and its allies, which are such excellent dyes for wool and silk, give only fugitive colors on cotton.
Then rub them through a hair sieve, and colour with cochineal.
The shades may be varied by the addition of small quantities of madder or cochineal.
Take two scruples of cochineal, and two ounces of argall finely pounded and sifted, and mix it with the liquor a little at a time.
Three kinds of cochineal are now met with in the English market: the black, silver, and foxy.
Half the sugar may be colored with cochineal to a delicate pink.
1580s, from French cochenille (16c.), probably from Spanish cochinilla, from a diminutive of Latin coccinus (adj.) "scarlet-colored," from coccum "berry (actually an insect) yielding scarlet dye" (see kermes). But some sources identify the Spanish source word as cochinilla "wood louse" (a diminutive form related to French cochon "pig").
The insect (Coccus Cacti) lives on the prickly pear cactus in Mexico and Central America and is a relative of the kermes and has similar, but more intense, dying qualities. Aztecs and other Mexican Indians used it as a dyestuff. It first is mentioned in Europe in 1523 in Spanish correspondence to Hernán Cortés in Mexico. Specimens were brought to Spain in the 1520s, and cloth merchants in Antwerp were buying cochineal in insect and powdered form in Spain by the 1540s. It soon superseded the use of kermes as a tinetorial substance. Other species of coccus are useless for dye and considered mere pests, such as the common mealy bug.
cochineal coch·i·neal (kŏch'ə-nēl', kŏch'ə-nēl', kō'chə-nēl', kō'chə-nēl')
A red dye made of dried, pulverized female cochineal insects and used as a biological stain and as an indicator in acid-base titrations.
