Why is my rhubarb crisp runny? ›

TROUBLESHOOTING: WHY IS MY RHUBARB CRISP RUNNY? It's pretty typical for any kind of fruit crisp to be a bit liquid-y while it's still warm. The juices are flowing and they are just thinner because of the warmth. But as long as you used the right amount of cornstarch, it should “gel” quite a lot as it cools down.

This article recommends poaching the rhubarb in a sugar syrup first and you can add flavors like vanilla, cardamom, star anise or even lemon to add a unique twist and a recipe for Vanilla-poached rhubarb pound cake.

Rhubarb is commonly used in both sweet and savory dishes. Although it's tart and acidic, it pairs well with sweet ingredients like sugar, fruit, honey, and sweet wine—which is why it's often found in desserts. You can use frozen rhubarb the same way as fresh: in sauces, pies, crumbles, and beyond.

Discard leaves and woody ends. Wash rhubarb with cool tap water, but do not soak.

So what's a crumble vs. a crisp? A crumble is just a crisp without oats in the streusel. It may feature nuts, but the streusel topping is usually a simple combination of butter, flour, and sugar that is more clumpy than that of a crisp.

Its stalks are deeper red and tinged with green, while its leaves are bright green. It has a more intense flavour and robust texture than the forced variety. Although it can be eaten raw, rhubarb tends to be too tart this way, and it's usually best when cooked with plenty of sugar.

You can add cornstarch or flour. I do this when making an apple pie and the filling is not watery.

Rhubarb prefers a pH below 7.0 (neutral to acidic — adding peat moss, compost, coffee grounds and Espoma Holly-Tone organic fertilizer can help acidify soil).

Sennoside A and other dianthrone derivatives are reported to be the active ingredients causing rhubarb's laxative effect (6). They are metabolized by β-glucosidase of enterobacterial origin and are converted into rhein anthrone, which produces the purgative activity.

To keep it sugar free you could use a little stevia, for a low fructose option you could use either rice syrup or coconut nectar, or if you're a honey fan, a little raw honey would combine beautifully with the ginger and vanilla.

Can I just chop and freeze rhubarb? ›

Yes, absolutely! Once washed, cut the lengths into rough 2.5cm pieces. Space out on a baking sheet lined with baking parchment and freeze until frozen (around 2hr). Then decant into a freezer bag or freezer-proof container and freeze for up to 3 months.

Stick to the stems if you're eating rhubarb raw—the leaves are poisonous. I repeat: Rhubarb leaves are poisonous. The leaves contain oxalic acid, which can be fatal to both people and pets if consumed in large amounts.

You can also toss sliced rhubarb with granulated sugar, which helps prevent freezer burn by minimizing the rhubarb's exposure to air.

To pick rhubarb, hold the stalk firmly, pull and twist. Do not use a knife to cut the stalks from the plant. The knife can carry diseases from plant to plant, and the remaining stalk can be a point of entry for other pests.

Maincrop rhubarb can sometimes have tough, stringy ribs, so after washing it, strip these off with a small, sharp knife and slice the stalk thinly or thickly as required. Forced rhubarb should be tender enough not to need peeling – just wash, then trim the top and bottom of the stalks and slice.

Instead, look at the length. The stalks are ready to harvest when they're between 7 and 15 inches long. The best time to harvest rhubarb is during the months of May, June and early July. After this, it's best to let the plant be, so it can regrow and recharge to survive the winter.
