Your tips for good meringues please

[NerdleNoodle]

Hello good people of MN - please advise.

I'm making a large batch of meringues for a party. My first batch has come out nice-tasting but the texture isn't great: very dry and brittle. Please give me your tips for the holy grail of meringues: crispy on the outside and ever so slightly chewy inside.

TIA

Hopeful bump

Old eggs make better meringues - by which I mean at least a week so. (Fresh eggs make better poached eggs, so there’s always an upside)

Wipe the bowl with half a lemon to make sure there is no grease on it AT ALL.

Add the sugar really slowly once the eggs are at soft peaks. A bit of cream of tartar or splash of lemon juice helps.

Cook in a really low oven and just open
the oven door a bit at the end and leave them to cool.

Separate the eggs in the morning and leave the whites at room temperature. Make meringues in the afternoon
Older eggs are better. Make sure each spoon of sugar is completely incorporated before adding the next.

Cook at no higher than 100c and then leave in the oven til it's completely cool.

Use a metal bowl wiped perfectly clean.

Try this from the Guardian. Mine tend to be too chewy so watching with interest.

This is what I do!
Old eggs, can be months beyond their date - the yolks become very fragile and the shells become harder to crack. (I use up to about 6 months old)
Make sure there’s no grease or trace of yolk. 2 fluid ounces to 2 ounces of caster sugar, use this ratio. If I’m batch cooking I use about 6 whites/12oz sugar.
Whites only in a large bowl, whip fast to very stiff peaks, slowly drizzle in the sugar while continuing to beat, add a splash of Camp coffee if you don’t want them pure white. To get crisp defined meringues be careful not to whip for too long.
Pipe or spread onto baking parchment.
Dry out in a cool oven, preferably overnight or as long as that.
They’re done when they easily lift away from the paper.
Sandwiching them together with whipped cream an hour or so before serving will let them absorb a little moisture to get the chewy centre.
Enjoy!
