1. Prepare Fruit: Select fully ripe fruit. Wash, then prepare exactly as recipe directs. If fruit lacks tartness add ¼ cup lemon juice when adding sugar. For separating juice for jelly, use 1-yard square of Canton flannel, spread over colander. Place prepared fruit in cloth, bring corners together and twist while pressing down on bag. To make jellies from dripped juice, use twice amount of fruit called for in recipe.
2. Prepare Glasses: Wash, scald, and drain the glasses and tin covers needed, and melt paraffin in a small pot over hot water while making jelly or jam. Use new paraffin; old paraffin often causes spoilage. If tin covers are not available, cut out circles of paper to paste over tops of glasses.
3. Measure Sugar and Fruit: Use the same standard measuring cup, holding ½ pint, level full, for both sugar and fruit. If sugar is weighed, weigh fruit also. To measure fruit for jam, pack solidly into cup until juice and fruit come to top. If there is a slight shortage, fill last cup, or fraction of cup, with water. If not quite enough juice for jelly, mix water with pulp in jelly bag and squeeze again.
4. Cook Rapidly: For quickest jelly making, use an aluminum kettle or saucepan—6 to 8 quart size. The kettle or saucepan should be less than one-half full of sugar and fruit to permit a full rolling boil, a boil which cannot be stirred down. Use hottest flame. If fire is slow, keep kettle covered after sugar is dissolved until mixture comes to a boil. Stir while coming to a boil, and while boiling.
5. Add Certo: For jelly, add Certo as soon as fruit juice and sugar mixture comes to a boil; then bring to a full rolling boil and boil hard for exactly ½ minute, stirring constantly. For jam, cook fruit and sugar mixture at full rolling boil for exactly 1 minute, stirring constantly; then remove from fire and stir in Certo. Time boil by the clock.
6. Skim, Pour, Paraffin: Skim jelly and pour directly from saucepan into clean, freshly scalded glasses. Skim and stir jam for 5 minutes by turns. This cooling helps prevent floating fruit. Ladle into glasses. Leave ½-inch space at top of each glass. Cover at once with ⅛ inch of hot paraffin. When cool, cover glasses with scalded tin covers or tightly pasted paper covers. Be sure to store in cool, dry place.
New Certo Users: Read carefully pages 4, 5, 17, 18, 31.

DON’T—double Certo recipes. Better color and flavor and more certain results are obtained from single batches.
DO—use fully ripe fruit of the best possible color and flavor. Taste fruit, and if it lacks tartness, add the juice of 2 medium lemons (¼ cup) when adding sugar.
DO—prepare fruit exactly as the recipes direct. Do not simmer before crushing or squeezing unless recipes specify cooking. For crushing fruit, a food chopper is convenient.
DO—measure sugar and fruit exactly with the same standard ½-pint measuring cup, level full; or weigh both. A standard measuring cup holds ½ pint sugar (7 oz. by weight) or ½ pint fruit or juice (8 oz. by weight).
DO—use a large enough kettle so that your mixture has room enough to boil hard. A kettle of 6- to 8-quart capacity is recommended. If the 6-quart size is used for jam, add ¼ teaspoon butter with sugar to reduce foaming.
DON’T—confuse a gentle simmering boil with the full rolling boil specified in Certo recipes. A full rolling boil is a high, tumbling boil that cannot be stirred down.
DO—time the full rolling boil by the clock.
DO—stir and skim jams by turns for just 5 minutes before pouring. This slight cooling helps prevent floating fruit.
DON’T—expose jellies and jams to dust or dampness after they are made. Spoilage is caused by the growth of yeast and mold plants, which are usually carried by dust. Use clean glasses, new paraffin, and clean covers. Paraffin hot jelly and jam at once. Fill glasses only to within ½ inch of top. Store in a cool, dry place.
DON’T—judge the texture of your jellies or jams too hastily. Certo recipes are designed to give an ideal set at the time they are most apt to be used. Many grow progressively firmer for a week to a month after they are made.
Do you know that pectin, which helps you make delicious jams and jellies, plays a role in medicine, too?
DOCTORS have long used apple pectin in the treatment of diarrhea—especially with young children. Good results here have led to further discoveries of the effectiveness of pectin in the treatment of many intestinal disorders and also in the dressing of wounds and burns. Pectin made by the makers of Certo is being used in several of these scientific studies.
BECAUSE this is a subject of active scientific interest, it seems to us news in which you might be interested. These facts are given solely as a matter of information. The makers of Certo wish neither to prescribe nor recommend.

Have you ever stopped to think why certain jellies and jams walk off with the blue ribbons in jelly-contests and win cheers from all the family ... just what does stand for perfection in a jelly or a jam?
The Bureau of Home Economics “Score Card for Jelly” rates jellies for flavor, texture, and color, and gives 78% of a score of 100 for perfect flavor and texture. Flavor is defined as “free from excessive sweetness, acid, or overcooked flavor”; perfect texture is “jelly that holds its shape when turned onto a plate, but quivers when the plate is moved.”
Certo jelly recipes are developed with fully ripe fruit instead of the under-ripe fruit commonly used in old-fashioned jelly making. They take you a long way toward perfect flavor. And Certo jelly recipes are designed to give best texture at the time the jelly is most apt to be used. They take account of the fact that many jellies grow progressively firmer for a week to a month after they are made.
About the ideal texture for jams there is far less agreement than for jellies. Some prefer jams that hold their shapes, others like softer jams. Either texture may be had with Certo jams. If a jam seems stiffer than desired, break it up with a fork before turning out of the glass.
The Short-Boil Method: Scores of state fair champions in jam and jelly making and millions of other jelly makers, too, use Certo and the short-boil method of jelly making. They know they can depend on Certo for sure results, time and money saving, and better, richer-flavored jams and jellies.
You may find that Certo recipes call for more sugar than you usually use. Remember that with Certo no fruit juice boils away in steam and you usually get half again more glasses. Thus the extra sugar takes care of the extra juice.
In any Certo recipe, 2 cups (1½ lbs.) of light corn syrup may be substituted for 2 cups (14 oz.) of sugar required. Results will not be satisfactory if more than 2 cups of corn syrup are used.
Mrs. A and Mrs. B both wanted to make some raspberry jam. Each had 2 quarts of berries to begin with and after cleaning and crushing them each got the same amount of prepared fruit—4 cups.
Both Mrs. A and Mrs. B started at 9 o’clock.
Mrs. A added 6½ cups of sugar to her fruit. Then Mrs. A simply brought her fruit and sugar to a tumbling boil, boiled for 1 minute, removed it from the stove and added ½ bottle of Certo. The jam was done and it had all of the flavor of fresh, ripe fruit.
Mrs. A was finished at 9:12.
Mrs. B added 4 cups of sugar. Then Mrs. B, following the old-fashioned “cup for cup” recipe, had to boil her fruit and sugar about 30 minutes before the jam thickened. This long boiling evaporated more than a third of the prepared fruit and carried off most of the natural fresh fruit flavor in steam.
Mrs. B was finished at 9:45.
Mrs. A got 10 glasses of jam from her 2 quarts of berries.
Mrs. B took 3 times as long and got only 6 glasses of jam.
Mrs. A had shown Mrs. B exactly what she meant when she said, “Certo really pays for itself!”
