General Purpose wine yeast
Yeast nutrient
Wipe marrow clean with damp cloth, then cut a piece off the stalk end of the marrow, deep enough to enable you to scoop out the seeds and pith from the rest of the marrow. Press the Demerara sugar into the cavity left; it depends on the size of the marrow how much you will need; a large one will take 7 pounds of sugar.
Replace the end of the marrow and seal with a piece of sticky tape. Then suspend the marrow over a jar or jug; something with a narrow neck so that the marrow can rest on this but not touch the bottom of the container.
After two or three weeks unseal the end of the marrow and add some more sugar; some of the first lot will have been absorbed into the flesh of the marrow. Put the end on again and leave for about six to seven weeks, when the sugar should have mixed with the flesh of the marrow and the resulting liquid will have dripped through into the jar leaving only the shell of the marrow. Add yeast and yeast nutrient. Strain into fermentation jar fit airlock and allow fermentation to finish until dry.
Keep at least twelve months when it will be very strong.
MARROW RUM (the alternative method)
This one looks good hanging in the kitchen for a few days! 4 oz of sugar per half pint of rum, White preferably, it blends better with the marrow. Get yourself a good mature marrow, cut open the top & scoop a good cup full out of the middle. Underneath the Marrow make about half a dozen puncture wounds with a sharp narrow needle (preferably long sowing needle or a sharp thin knife ), & suspend above a glass bowl . Feed the marrow through the top hole with sugar & rum in proportion & in a few hours you'll get lovely scented marrow rum dripping out of the bottom. An average marrow will normally take about one & half pints of rum (over a few hours) I prefer to make most liquers on the tart side & sweeten to taste afterwards if necessary. Geraint
Marrow Rum
This is going to be impenetrable for most of us colonials, who don't know a "marrow" is Brit for "squash", or Zucchini. You can make a kind of wine by filling the cavity of a hollow vegetable, such as a pumpkin or other hollow squash, with fermentable sugar, nutrient and yeast.
Pectic enzyme will also help, or better yet, a starch-converting enzyme, such as Koji, or Diastase. As fermentation proceeds, the sugars in the squash will be fermented, and the whole thing gets digested. Best to do it in a container, since it may eat through the outer skin. You can do it with either beer, or wine. If you use something like a large pumpkin, and carefully cut a round hole as you remove the stem, it is possible to fit it with a fermentation lock. Then pour in any basic must or wort, grape juice, sugar water, whatever. Add a touch of yeast, and away it goes. Draw a happy Bacchus face on the pumpkin !
