Rose-Hip Jelly No. 1
Take a large quantity of well-ripened rose-hips; wash them in a colander and dry them. Slit them lengthwise; remove the hairs and pips with a sharp penknife; weigh the fruit, and place in a pan with enough water to float it, and a pint of sugar to every pint of fruit. Boil all together till quite soft, and strain off the liquor, which must be boiled up again for a few minutes and then poured into pots.
Rose-Hip jelly No. 2
Proceed as above, but, having prepared the fruit, cook it till tender in a very little water, then strain off the juice and measure it, as for other jellies. Boil it up again for ten minutes, add one pint of warmed sugar for every pint of juice, and cook until the jelly sets.
Rose-Hip Marmalade No. 3
Prepare some ripe rose-hips by washing, drying slitting open lengthways, and taking out the pips and small hairs; weigh the rest; place in a preserving-pan, just barely covered with water; cover up and cook slowly till tender. Add an equal weight of vegetable-marrow chipped very small, and sugar equal, or almost equal, to the weight of both together - i.e. for four pounds of rose-hips and four pounds of marrow, seven pounds of sugar would be ample. Boil for an hour.
