Grantlee63,
1 lb of Honey contributes approximately 0.037 to the SG in 1 gallon of water, or 0.0074 in 5 gallons. You want to increase your gravity by 0.010 in 5 gallons.
Therefore, you will need: 0.01/0.0074 = 1.35 lbs of honey.
Or, you can just take a measured amount of Mead, put it into the hydrometer tube and start adding measured amounts of honey, dissolving it completely by mixing well, until you get the SG you are looking for.
Or, take a measured amount of Mead and start adding measured amounts of honey until you get the taste and sweetness you are looking for.
Hope this helps,
Angus
P.S. - If you are dissolving the honey in water first, the above calculations are off.
