You should try it. An emergency situation is no time to find your survival food makes you puke.
Lidl stuff is surprisingly good quality and like the joke goes; the dearest thing is the pound you put in the trolley and you get that back!
Just buy some more...
I've already tried Halva a few years ago whilst I was out in Cyprus so it won't be a surprise. I'll wait until the Walker's Shortbread has been depleted before opening the Halva. Lidl keep packets of the highly dangerous Walkers Chocolate Chip Shortbread (even more dangerous than Pringles) near the checkout at my local Lidl but I was able to get through the checkout without grabbing a packet this time.
Some other quality bargains to keep an eye for in Lidl are;
Milbona 400 gram Tin of Instant Skimmed Milk Powder, which is actually the only reasonably acceptable fresh milk substitute for black Tea I have come across.
Bellarom Vacuum Packed 500 gram Coffee Gold (100% Aribica).
Arriba Superier 81% Cocoa Dark Chocolate.
Cimarosa Paarl Pinotage 2008 (South Africa). (got a half case for just £18 just recently
)
Tawny Port Armilar 750ml. (still good value after the recent price rise, but still less than £6 a bottle)
Wychwood Hobgobblin 500 ml beer only £1.09 ($1.75) at the moment.
Ben Bracken 12 Year Old Malt Whisky (Which is actually rebranded Speyside Tamnavulin 12 year old)
Perhaps I should make a request to Lidl's to see if they could start stocking Red Feather Canned Butter or a similar product as I cannot find it anywhere in the any of my local supermarkets.
